IF money is a major issue with you, as it seems to be, then please consider F600's which is the next thread below yours on this forum. $35K for a new car or about $15K for a used one - front sports car nose along with a diffuser (sp?) for aerodynamics. It is a budget class with rule restrictions for cost control. You can also go here for the pro series - www.theformula600challenge.com As always, become an informed consumer BEFORE investing in any car by reading all you can (on forums, etc) and getting hands-on experience by volunteering to crew for a nearby driver. Even then, rent a car for your driver's school to see if this is what you love doing.
Been messing with these cars since 1982
