Start off at community college, and you won't have to worry about a bad high school GPA affecting you. Knock out all of your gen eds in community college, boost your GPA up by focusing on classes (if you try, you will at least make a C in those classes), then transfer to a 4 year school if you still feel compelled to continue your education. Transfer requirements are much more lax then admission requirements, plus you get priority over incoming freshmen provided you goto a 4 year school in VA.

Personally I seriously thought about being a tech, but the only thing that stopped me was that while I thought I would enjoy it, I thought in the long term my body would start giving out and as I got older it would be rougher and rougher to always be laying on my back or bending over working on a car or truck all the time.

To the person who was interested in working for Ferrari or a high end exotic car dealer, my advice would be go to school, get As or high Bs at the very least in all of your automotive classes, graduate with a GPA that is above 3.60, get some on-the-job experience working for BMW, Mercedes, or a "lesser" luxury car dealer, while your at these jobs develop a reputation as being a damn good tech, then after 5 years or so go after Ferrari, Lamborghini, etc. tech positions. Develop connections thruout the local area auto industry, and the national auto industry as well. The competition WILL ALWAYS be fierce to work for those companies, but if you get a position there I imagine their name on your resume would make your career potential limitless.
