SPOTTER'S GUIDE                                                   Eldorado 1979-1985

There's no denying the '79 Eldo was a major sales success. It really was the right car at the right time for Cadillac, and the styling and proportions hit a sweet spot. In usual GM fashion, they painted with broad strokes first, then refined the details. It's hard to argue with that approach, especially when you're focused on differentiating yourself initially from the sister cars, Toronado and Riviera.

Contrary to the oft-repeated conviction that these Eldos are all the same "except for engines", there were significant changes and improvements made almost every year, in addition to color, styling and interior/exterior refreshes detailed below. If you're so inclined, check out the Engineering Changes by Year page for the full story.

Below is a summary of the yearly exterior and interior changes for "spotting" purposes.

Quick Links:



  • Unique horizontal pattern grille that's spring-loaded for impact without damage.
  • Matching 1-year only smooth chrome grille cap w/ Cad script

  • Chrome “corporate” dome/map light pair (visors use an old style catch since the integrated dome light didn't appear until '80).
  • Unique Speedometer (stubby turn signal indicators, no 55 MPH callout, lots of graduations on face) See Speedometer History for details.
  • Driver & Passenger door controls are unique for '79; power lock and window switch locations are swapped. Appears to be same part as used on Riv '79-85.

Speaking of Power Seats...

While a 6-way power seat was always standard on the driver's side, a power-operated passenger seat remained optional ($197.40 in 1985). Occasionally, a manual version pops up in the wild, though they tend to favor the earlier years. Power Recline was also an option, with the switch mounted on the lower seat trim.

Manual Seat Eldo. Rather than a block-off plate, the entire panel is a unique P/N

New for 1981 - The first car to have power memory seats since the 1958 Eldo Brougham

Grille Header Updates

We interrupt this spotters guide for a quick look at grille cap changes.....

It follows that radiator grille caps would update to match yearly grille changes, but I discovered a couple interesting things at play. 1979 obviously has a pronounced lip that favors the early spring-loaded grille. This was revised for the fixed '80 & '81 design which adds a bit of a taper over the primary area to minimize that lip, adds a brushed appearance, yet maintains the Cadillac insignia. For 1982, something curious happens...despite looking like the '80/'81 style, the cap itself is a 1/4" shorter in length on each end (see center pic). On further inspection, it also has a greater trapezoidal appearance on the ends, and note the reduced spacing between the top of the 'C' in Cadillac and the black infill relief.

Stranger still, the hood itself changed for '81, not '82 (you'll find "81" stamped into the underside sheetmetal, as well as the fender-to-header brackets). Perhaps this was in reference to Calendar-Year '81? From my measurements, the '79 hood measures 15" on each side up to the point where the hood begins angling forward, while an '84 hood measures 15-1/4". One would assume the hood change would match the grille cap length change? Curiously, the parts manual shows a single hood part number for '79-85.

1979: 1613972
1983-85: 1623988
  1980/81: 1618907 Note length difference to '82. 1982: 1621314




  • New grille style that's carried through to '85
  • Cad script remains on header for '82, yet is actually a new grille cap
  • Carryover Park Lamps: amber and divided
  • New taillight applique with colored infill (through '85)
  • First year for HT4100 fender badge (Diesel and V6 still available)
  • Eldorado Touring Coupe package first offered. See the ETC Page for More Info.

If the grille header says Cadillac, it's pre-'83.
If the fender has a V6 badge, it's pre '83 but post '80.
Silver ETCs are always '82


  • Carryover "Teakwood" woodgrain and steering wheel design
  • Front seats now accomodate 3 passengers with a 45/50 design.
  • Glovebox door is revised to eliminate perimeter screw heads.
  • New Climate Control with outdoor temp feature  - shown in pic below. Mirror-mounted thermometer dropped.
  • MPG Sentinel becomes "Fuel Economy Data"; loses the V864 CYLS function.
  • First year for THM 325-4L transmission which necessitates new PRNDL.
  • ETC interior is silver/gray leather bucket seats and console; only year for that color.



Largely a carryover from 1982, with these differences:

  • Park lamps are clear (through '85)
  • Grille header has same dimensions and appearance but Cadillac script is eliminated; moves to grille (through '85)
  • Door handle grip & pushbuttons gain radiused corners (through '85)


  • Carryover from 1982, including steering wheel design
  • Bose dual-shaft radio option offered (1-year only in this config). See Sound System section for more on this.

1970's style button gets an update.
Inner mechanism also changed.

1984 / 1985


  • No major exterior changes for '84/85. Looks like an '83 but will have no fender badges.
  • Convertibles make a factory-endorsed return, conversion was performed by ASC in partnership with Cadillac (see above).
  • A full-Cabriolet roof treatment is offered on Eldo & Seville (simulated convertible top).
  • A Commemorative Edition Eldorado (and Seville) were offered in '85. (4VU $1241). These were available in Cotillion White or Commodore Blue and have two-tone blue and white leather interiors. Exterior emblems are gold, with a special medalion. Wire wheel covers have gold centers. The taillights have NO applique, and are basically 1979 lights.
  • Aluminum rims are still offered, but are no longer color keyed for '85; all are silver.

ASC convertibles are always '84/'85
Bordeaux Red ETCs are always '85.
Sable Black ETCs with silver aluminum wheels are '85.


  • New seat pattern for base Eldos. Biarritz seat pattern remains consistent, 1979-85.
  • Door panel woodgrain inserts (both of them) lose their silver trim border for black (see '82 red interior above for silver example)
  • Steering wheel left and right horn pad surfaces gain a (much needed) perimeter relief
  • 1985: Auto-Dimming rear view mirror offered (Toro first in '84)
  • Commemorative Edition (1985) will have a unique steering wheel horn pad center with gold insert, and the obvious 2-tone blue/white leather seats and door panels.

    Dashboard internal structure redesigned to accommodate:

  • New Delco 2000 radio introduced (1984)
  • Fuel Economy Data becomes Fuel Data, dimensions change to match Climate Control panel width
  • Dash loses plasti-chrome surrounds; headlight knob updated to match radio

New base-model seat pattern, updated horn pad, revised dashboard with Delco 2000 radio, Fuel Data display and black trim. Note non-leather wheel.

2-Tone Commemorative Edition with exclusive horn pad.

Note gold wheel centers, borrowed from Seville.

Memory Seat option not available on convertibles due to quarter
window switch control location.



Exterior Summary:

  • 1979-'81 easily identifiable by yearly grille change
  • 1982 looks like '82-'85 except for amber park lights and Cadillac script on grille header
  • 1983 looks like '84/85, except it will have fender badges
  • 1984/85- No fender badges; indistinguishable unless it's an '85 Commemorative Edition or ETC with unpainted wheels.

Interior Summary:

  • Analog ATC is always a '79.
  • Lowboy or "Riv" style console is always an '81.
  • Digital CC & a passenger rear door handle is always 1980. Or...if you only can see the dash, a 2-button MPG Sentinel is a giveaway.
  • Digital CC (without outdoor temp) & no passenger rear door handle is '81. Or...if DEFI equipped, MPG Sentinel will have a CYLS button.
  • 1982 & '83 have dual-shaft radios and the updated Climate Control with Outdoor Temp.
  • Delco 2000 radio is always an '84/85. 1984/85 also have a unique seat pattern on base Eldo.
  • Auto-dimming rear view mirror? It's an '85 exclusive.

Wheelcover options also changed yearly, with some spanning multiple years. However, since these are easily changed, it's tough to rely on them for ID. Same with a pre-'84 that's had a repaint and badges were omitted.

There was also a dizzying (and ever-changing) array of exterior, interior, and top colors offered throughout the run. A real pro can identify a particular year simply by a unique color or 2-tone combo.

Once again, if you're interested in the yearly electrical, mechanical and design changes, check out the Engineering Changes by Year page.

What's with the WOODGRAIN?

My gut feeling has always been that 1980/81 woodgrain was different than 1982/83, and possibly 1984/85. But after spending some time with the parts catalog, I'm beginning to question that. Cadillac referred to the pattern as "Teakwood", and from a cursory review of internet images, it appears Cadillac didn't just crank out the same identical pattern on every car, but actually had multiple patterns of the same "species", all sharing the same part number. Since we know there were changes to the physical glovebox door mounting scheme, the p/n break isn't useful in determining a woodgrain difference. So, I took a look at the woodgrain-patterned glovebox door surround, and learned the same p/n was used from 1980 through 1983 (1617442). The p/n changed when the silver border was dropped for black (84/85).

Have a look at this random assortment of glove box doors. Mentally normalize the various color temps and examine the patterns... not one of these repeats.

Out of curiosity, I then compared three center panels I had on hand from '84/'85 Eldos and discovered the same thing. Identical "species", each with its own unique pattern. Maybe I should've grabbed that '82 glovebox door last time I was at the yard....

Drivetrain Emblems:

1979 & 1980 Fender Emblem unless Diesel was ordered. Adhesive-backed.
