Which car is best for you is something only you can decide. Your budget allows you to find some really beautiful cars, again which one you buy is up to you. Personally, above and beyond my 427SC ERA for sale in my signature line, there is a absolutely stunning 427SC Contemporary Cobra for sale at the attached url below this line that to me the best bang for anyones buck.
