1985 Buick LeSabre Collector's Edition 307 Olds, Quadrajet 4bbl from North America


If you're looking for V8 mileage, comfort, and reliability, the '77-'85 LeSabres are the ticket


Electronic Climate Control light is always blinking, but A/C and heater still work fine.

Lockup on torque converter for overdrive is fudged up... Need to fix that soon. Trans is 2004-R.

Quadrajet carb needs a rebuild soon, and it's current state is really hurting my fuel mileage.

Wiper switch is finicky. All these electric or electronic parts like to go for a dump at least once in a lifetime. They are also very expensive and hard to find.

Like all other GM Mid '80's RWD's, the rear frame rails will eventually rot out. They're toast on my dad's '81 LeSabre. Oil sprays and car-washes are mandatory if you live in the rust belt.

General Comments:

This car is totally comfy! If you position the power seats correctly, it feels like you're in a recliner! Lots of room, and did I mention comfy?

Electronic Climate Control (ECC) and all the power options make you feel like you own a car newer than what it is. ECC is a neat feature when it works properly.

The 307 Olds is a total dog. No horsepower and even less torque. That's why I'm contemplating the Buick 455 swap. It's fairly cheap to do and will make a nice sleeper. Plus, if you locate a Monte Carlo SS or Grand National 2004-R, it will bolt up to the 455! Big block and overdrive! Otherwise, the 307 is great for mileage and reliability when tuned correctly (a 2bbl carb will help mileage greatly).

Try and find a set of the 5 spoke road wheels. They really set the car off nicely. Also find a set of winter wheels/tires to keep the others clean.

Personally, I prefer the 4 door over the 2 door cars. They have a cleaner look, easier back seat accessibility, and don't have 3 ton doors.

A wiper switch is not worth fixing? Until recently they cost less than $80 (for the ones with cruise on the stalk to), and less than an hour's worth of labor to install.

Also to get the wipers to stop, you can simply pull the fuse too.

I've had several 307 V8 equipped cars, mostly Olds Delta 88s, and while it is true it is perhaps slightly slower than a 305 or even a 302, it is not a 'total dog' in my experience. Acceleration was quite adequate, and off-the-line torque response was quite good.

If the original poster has been swapping around carburetors (he mentioned a two barrel instead of the original four barrel) this might explain slower than normal performance.

There was no 2 bbl version of the 307 Olds ever.

The 1980-1984 307's were not too bad. The 1985-1990 ones were much worse. They have different heads. Do some research.

A 2-bbl carburetor wouldn't even work on this car, as everything is computer controlled, including the carb.

Big reliable car


Rebuilt engine at 250,000 km due to flooding carburetor, causing a main bearing to prematurely wear out. But I could have continued running the engine indefinitely.

I'm on my third rad and third water pump.

Most of the front suspension parts have been replaced over the years.

Three sets of front rotors and pads.

Replaced original rear brake drums and all rear brake components at 350,000 km.

Rust in floor-board, rear wheel- wells, rocker panels, front door posts and roof.

Vinyl Roof deteriorated and was removed.

Paint started to fade so it was repainted in 2000.

General Comments:

This car spent most of its life in Ontario where they salt the roads every winter. I had the car sprayed with oil every fall so the car is still solid. All the rust spots were small and repairable with new metal and fiberglass. Every mechanic comments on the good condition of my vehicle.

I don't plan on buying a new vehicle any time soon. The V8 engine is running strong and the car handles well with 205/75/R15 's on the front and 235/70/R15's on the back.

I have driven this car from Toronto to Vancouver three times in the winter using Yokohama all season tires. I got caught in a blizzard on I90 somewhere in Minnesota and had to run for twenty miles on a closed highway. Also I've driven all day on pure ice, passing numerous 4X4's in the ditch.

This is an excellent highway cruiser. It will run all day at a hundred miles an hour pulling a trailer. The trunk is huge.

The interior is crushed velvet with fake wood everywhere and chrome which is very cool. Also armrests which fold into the seats and seat-belts for six people. The front bench seats split for a drivers side power seat. It's a very comfortable ride. Everybody says how smooth it runs.

The Olds 307 motor is stock except for a chrome air-cleaner which makes a nice sound when the four-barrel kicks in. It could be more powerful, but the gas mileage isn't too bad for a large car, 18 to 25 mpg if you don't race. It comes equipped with a four speed auto which is very nice, at legal highway speeds the engine sounds like its barely working.

Overall I'm very happy with it.

I have just bought a 1985 LeSabre Collectors Edition, 85 000 original miles. I am the 2nd owner; it was stored in a garage for the last 10 years.
