I bought it with 181k and 2 owners. 5.0 liter V8 that I got as high as 31 mpg hwy 21 mpg city. Extra cool AC and smooth as silk to drive. It failed to pass emmision requirements in my area so I sold it with 358k on the odometer. It still run and drove like a new car. I always regretted letting it go and definitely would buy another one in good shape.May 21, 2022

Loved it it was a very good first car. Loved it because it was my very first car. Loved driving it. Loved off-roading, mudding, and drifting it just in a few inches of snow. The thing that I loved the most on the car were the breaks-the front ones, it always stoped on a dime.Apr 24, 2013

The car may move slow with the weight it has, but with the v8 under the hood, she could make some smoke ;-). Since this was the first car I drove, and it was sitting in a garage for most of its life, it needed some serious repair in the gasket department. Once we found the problem with the header gasket, our problems were fixed. The interior feels like sitting on a couch, but the front seat headrests are missing. Because the thing has a v8 the gas mileage is poor and you tend to develop a lead foot to get it moving. all in all, the car is very comfortable to drive and I would recommend it to anyone that finds one.Jan 06, 2012

I have two. An '88 and an '89. One black, one white. These have been the best cars I've ever had. I inherited the '89 from my grandmother back in '97. I drove the car daily until '08 when I bought the white one to keep the miles down between both of them. The build quality, smooth ride, quietness and overall comfort of these cars is unmatched by today's cars. Over the years, I've had to rebuild a transmission on one and the torque converter on the other. Otherwise, just basic maintenance. (tuneups, oil changes, batteries, brakes, tires, a.c. service, cooling system service, mufflers/tailpipes, etc..) This is definitely the kind of car to go the distance and last through the years. A good car to have if you're trying to avoid all the expense of buying new.Dec 18, 2011

the performance of this car is great, it is very responsive, while it does not haul a$$ it gets on down the road, and the braking is great for a big sedan.The build quality is great, I drive it down dirt roads and it does not squeak or rattle any.The appearance is nice for an 80's model car, it is whats expected for it's generation.This car averages anywhere from 20-26mpg and this is one of the most low maintenance vehicles I have ever had. This car is fun to drive, it's like being in a time capsul taking you back in time, and enjoying true comfort as you go!!Nov 14, 2010

This was my first car. It looked great and was in excelent condition. I had to replace a lot of thi9ngs and about a year after I bought it the transmission started slipping so I sold it. Over all it was a descent car however the amount of repairs, the poor gas mileage, and the poor performance and acceleration make me glad that I sold it.Nov 22, 2008

We bought this car from a guy that treated this car like garbage. That's probably why it gave us so many problems. The car burned oil badly, about a quart every other day. 18mpg city. Poor stereo (only am/fm) The car could take a beating (physically) The drivers door eventually got stuck locked and the passenger door didnt lock. The transmission was giving out so we sold the car for a buck...wfound out the transmission finally died a few months later. Nov 03, 2008
