So I bought a 95 grand prix with the 3.1L engine for $850 with 201,000 miles in November. Since then I put about $700 into the car and now I need a new intake manifold. The car still drives, but I'm broke. I was told there is an additive at like autozone that could make it last longer so I'm gonna get that no matter what I do. Should I sell the car asap hoping I get like $800 for it and just get rides to work while I save money for a new car, or should I keep driving it till it gives out completely and use what money I saved over that time with the money the junkyard would then give me?? Please any feedback will be greatly appreciated. (I only make like $580 bi-weekly part-time, the only expenses I have are gas and car insurance at the moment) I want to get another grand prix 98 or newer with the 3.8L
