This car was produced during the wide span of years that GM FWD's were all poorly engineered garbage. It was unreliable from day one-to purchase one for anything much over scrap value 20 years later is a bad idea. Here are just a few reasons..
1) Almost any FWD V-6 has several items that are difficult to maintain due to the engine being mounted 'sideways'. This engine will need a lot of unscheduled maintenance that will be difficult due to it's lateral mounting.
2) The AC does not work. If it does, it will fail soon. Don't fall for the 'it just needs to be charged' pitch. I guess there is a small chance that the system was properly repaired.
3) If it has power windows, ALL of the window motors will fail at some point.
4) Most GM cars that were produced during the infancy stages of DEXTRON coolant integration have had traditional 'green' mixed it and will have issues due to this.
5) Unless it was a southern car or only driven in the nice weather where you live, it probably has significant rust damage is places that are not always easy to find. Fuel/brake lines are a good example.
I purchased a 1995 Toyota Corolla with 150K in 2007 (so it was 12 years old at the time) for $2200. I drove it until 2013, racking up over 330K doing nothing but routine maintenance. It would not pass inspection at this point due to a rust hole in the floorboard, however it drove down the road just fine. Given the fact that I NEVER (literally) washed it and drove it in Upstate NY winters this was to be expected. I was leaving for overseas work at the time inspection was due, so I just gave it to a friend. The AC still blew cold, heat was hot, no check engine lights, etc.
Sorry if this message comes across as condescending, it is just the harsh reality of GM FWD's from the late 80's to the mid 2000's. I truly don't want you to make this purchase, you will regret it.
