Replaced the radiator at 82,000 miles.
Replaced the muffler system at 82,000.
Replaced the flange at the crossover pipe - rotted out at 82,000.
The car rides like a dream, smooth going over bumps, barely notice them.
Acceleration is responsive.
Getting 22.8 miles to the gallon on highway, 18 miles to the gallon in city.
Body and frame hold up very well.
Interior is like a Cadillac - velvet seats and lots of padding. Roomy, can fit up to six people in the car very comfortably.
Mechanically is very sound. Owned it for two months, not too many things have gone wrong besides normal maintenance.
If your engine is really a 301, then it's not a 4 bbl, it's a 2 bbl.
(I own a 78 LeSabre with a 301)
I have owned three 80 model LeSabres. I know GM diesels have a bad name in general but the 5.7 liter diesel engine in the black LeSabre I currently own is the single toughest engine I ever had in a GM product. All in all, EXCELLENT cars.
I own a 1983 LeSabra Limited, The car is truly ugly.
I have found my 307 very dependable. The TH350 works well and is a compliment to its builders. Interior is very roomy and comfortable. The right rear door lock does have some electrical problems. On a whole she handles the Alaska winter very well. Good traction, wonderful ride on bad roads. With all the SUV's on the road I feel safe in her large cabin.
Regarding the first comment I read, the 1980 301 engine did in fact have a 4bbl. Quadrajet carb on it. A 2bbl. was not available probably due to the extreme lack of performance it would have had with all the smog junk on it. I have owned my 1980 Limited Coupe for three years now and have found the 301/TH350 combo to be reliable for daily use. All in all, a comfy old cruiser that I plan on holding on to.
