I just wanted to know if the above car is good and if the car is worth buying for around $3,500 and if its worth putting performance parts in. Thanks

if the engine is in good condition then go for it

How many miles? What conidition?

If you can find a good one, they are great cars.

I have a 1993 325is with 130,000 on the engine and has been very reliable with low (considering it IS a BMW) maintenance costs overall. Other than brakes and tires, the tranny is still solid. I plan to drive it until it falls apart!
