Hey, so I am probably going to be purchasing a 91 gt4 st185 in a couple of days and im looking for a little help as i've searched everywhere and not gotten the straight answers i was looking for.. -how is the gt4 to maintain, expensive ? insurance is high? -are the parts hard to find? and can i take parts from a 91 gt or does it have to be a gt4, please give as much information as you can so i can soak it up before buying this car.
