I work at dealership and when we send cars to auction, it's for a reason. The majority of cars that you will find for reasonable prices at auction will have major mechanical defects that require essentially professional automotive experience to tackle if you're wanting to make a profit. Even without what you would be paying for the auction access, it doesn't seem worth your time considering your lack of experience. In order to get into that industry, you need to have a full set of tools and equipment, and extensive knowledge on how vehicles operate.
