I got a 89 Geo spectrum car myself too. I bought it brand new back in June of 89. I like the car cause it really save me a lot of money on gas. it has been a good car. but I only had a trouble a few time. I work on it myself and I am getting better at fixing it too. This car I have got has got 317,000 miles on it. I am still driving it too. I am gonna see if I can find me a really good rebuilt motor for them. The car got a lot of miles on it and I won't complaint about it. It is getting where it want to burn or use the oil. I am gonna try to find me a good rebuilt motor for that car. and maybe I can get another 300,000 miles on it. so if you keep the oil change like you said it will last you a long time too. that's what I did.
