Is there a difference in paint quality over..., between the celica st and the gt... Options

[FiraMica]

I was just wondering if they was a difference in paint quality because I found a 94 celica gt with the same white color I got on my car (94 celica st). Grant it my car is a coupe and his is a liftback, but we had wash and shined our cars together (not at a local car wash but in a mutual friends yard)... We used the same products and all but his car shined better than mine and if I had buffed mine any farther it would be swirl mark city... We took the same (almost) amount of time, so how could his be any different...
