Change of car , Good or bad idea

I currently have a 95 honda civic coupe with 120k miles on it and im lookin into buying a dodge stealth or mitsu 3000gt probably around a 92 . with about 100k miles on it . Am i stupid for doing this ? I can prob get one for about 5-6 grand SL version ..premium sound..leather etc. Any suggestions ?

keep the honda till it does.. which will be a while.. save some money.. and then put it into a 3000gt vr4.. :D
