chimp or griff?

[kartman24]

okay i guess i should put a flame suit on asking this in the chimeara forum, but i`m looking to buy a TVR up to £15000, what is the advantage of one over a griff, anybody on here owned both? which would be your choice? also i haven`t driven either car yet, how could i go about trying both out to see which i prefered? final question for now is what is the difference between a standard 4.litre and an HC engine (big valve heads?)----martin
