ok the first one is im getting a chunk of cash and was thinking about buying the all love gt4 from canada but i was wondering whats a legitament price one guy wants 10999 and the car has under 99000 km is that a good price ?

secondly i heard about a gt4 that had over 800 hp using a twin charging system . should i think about going that route or just keep it basic . If i decide to go that route what is it that i will need and how much should i expect to drop in it just wondering
