Ok here's the scoop I own a 1990 honda civic si the body has a good bit of rust. It has 241000 Km on it and the head gasket just went the head might be warped. I have a mech. that says he can rebuild the engine for Approx $1500.00(canadian). Should I do it or not the main consideration is the rust damage to have it done Pro is about 6500.00 including paint, and that is new panels not a cut and paste job. I could do it myself for under 500.00 cut and paste. It also has a new rad less than a year old and brand new front axles. I bought it used for a $1000.00 and have already put about $3000.00 to $4000.00 into it. So do I go buy a new car or put the cash into it?
