The first question is what is your budget? If you're looking to spend 25K, I wish you the best of luck and suggest that a Cobra isn't what you want because if you can find one it'll be a severe disappointment for that price. If you're looking to spend 100K there are tons of quality cars that can be had for that price. This is a car that truly is you get what you pay for.
