Hi all. I'm new to the forum. I currently own the cars in my sig plus my wife's Civic daily driver. I used to own an 86 GT about 9 years ago when I was in high school and I always wanted a 91-93 LX. Anyway, I found one that's never been driven in the weather and it also happens to be a yellow feature car with black top. It's in immaculate condition and the guy is asking $9500 for it. If I get it I'll just sell my VW and daily drive this car for a while until I can find a decent beater for winter months. I've been trying to look for some good sites with info about the differences between the 86-95 cars but I haven't found much. For example, I'm trying to find info on which years had forged pistons, etc. Can you guys give me any info or point me in the right direction? Also, let me know if you think the guy is asking a fair price for this car. Thanks!
