Here’s what I learned:
1) If you are not mechanical, bring someone who is.
2) Make sure to take your time and inspect everything.
3) Run the vin number to make sure that the mileage is as advertised, and that the vehicle is paid-off.
4) Research to make sure that you can pay for the fuel bill, insurance, and maintenance.
5) Sleep on it and really make sure that you want the vehicle.
6) When you perform any cash transaction, do it at the bank so that they can check the bills for legitimacy.
