"First time buyer" generally refers to a buyer with no or very limit credit experience. I'm assuming you have other forms of credit that's been on-going since you had your car loan. If that's the case, you woldn't be considered a "first time buyer".
Just an example, i deal with Honda. Honda Finance considers customers with at least three lines of credit. It can't be a student loan or something derogatory such as collections is not considered a line of credit.
