ok i have an 83 gsl and i had originaly bought it for $550. its a great little car but lately i have had some problems with it. i need a new tranny cause my main bearing is shot, i need a new light and turn signal switch cause my burned out. i had replaced the engine with one that had 65,000 miles on it. when it starts up it burnes coolant untill it is warm. i have a loss of power. but it still gets up and goes. i need a new left front fender. i can still drive it just fine. last week i drove it to the wisconsin dells. i also have a 79 parts car that i have kinda used for my 83.now it has a RB (front to back)performance exhaust, a custom hood that i built, custom taillights, i even built a custom sub box for behind the seats. i have a clean title. so what should i do with this car and if i was to sell it how much do you think i could get for it?
