Costs pretty much the same, both top notch condition. G60 is rarer, but mk1s are becoming pretty hard to find in good condition. Both are pretty old cars, mk2 is 1991 and mk1 is 1983. I'm car mechanic so fixing is no problem. Perfomance wise mk2 is way faster, pushing around 210hp and mk1close to 70hp. Hard time choosing between those two..
