1976 Cadillac Eldorado Biarritz 8.2L, 500ci V8
Summary:
Extremely comfortable, and powerful with slight mods!
Faults:
Replaced alternator, power steering hoses, fuel pump, all fluids, brakes, shocks, and tires when I received the car. I also rebuilt the carburetor. It had not been on the road for many years, and still had the original tires on it.
General Comments:
This car had not seen the road for many years before it became my daily fair weather driver. Some items I replaced preventatively (e.g. fuel pump), though others needed attention when I bought it.
Now brought up to snuff, the car has been nothing but reliable in the 12,000 miles I have driven it.
When I bought it, the car was a dog -- it couldn't get out of its own way. I replaced the vacuum advance diaphragm in the distributor, advanced the base timing to 12 degrees BTDC, removed the clogged catalytic converter, removed the resonator, and plugged off the EGR. The car is now seriously quick for a 5400 lb land yacht. It runs 0-60 in about 8 seconds by my stopwatch -- no joke. The stock 0-60 time is about 10.5 seconds for this car. I have used no non-stock parts to obtain this performance. The car feels faster than my 1972 Deville with a 472 (which has received similar mods), even though the 76 Eldo engine is rated at 190hp stock vs. 220hp stock for the 72 Deville.
I almost sold the car several times (I have 7 other cars--just too many), but kept it because of its sheer comfort. I simply ooze into the seats. Ride quality is excellent. Car just soaks up the miles.
Believe it or not, I consistently get about 16.5 mpg at 70 mph if I stick to all freeway driving. I never thought I would see this kind of mileage with a 500 ci monster under the hood, but I consistently achieve it on a daily basis, as my 100-mile round trip commute is all freeway driving. My 72 Deville struggles to get 13 mpg on the freeway.
The sunroof is a bit leaky in a heavy downpour, but I absolutely love this car.
Would you buy another car from this manufacturer? Yes

Dual exhausts make a car look cool. However, you won't get any better performance unless your engine is revving to 3,500 rpm or more. Duals might increase your H.P. ever so slightly, but you will lose some torgue. Also, on duals, the mufflers will rust out sooner because the muffler is not getting hot enough to thoroughly get rid of all of your H2O coming from your exhaust system from the warming and cooling. On my car, the single exhaust lasted twice as long before rusting out compared to the duals I had on.

If you have removed the catalyst, you may as well run dual exhaust to get the most improvement.
