Re: limited top speed
Your numbers are correct, lord-quas. The Crossfire is wired shut at about 155, maybe a few MPH above, from my brief experience with the car. There is a much longer discussion in the forum [skimmed it a few days ago] that goes into the whys and wherefores on the subject. Just use the 'search' function.
Can't offer any thoughts as to why your seller is mistaken, sinister or no, but the Crossfire is a swell car. I've had mine for just a week or so and love it. Lot's of great info here, so keep up with your homework AND GO BUY ONE!
