Looking for an older gay movie title

[mostlytx]

It's a "classic or vintage" movie I had years ago and lost, not it seems to have disappeared. Since I don't know the title or the names of the people in it - it makes a search difficult.

The movie starts out with two blond guys coming out of a school dance, both in suit & tie and complaining that their gal wouldn't do anything so one guy tells his buddy he'd help him.

There are 4 or 5 scenes, one of a guy being told he has to pay the garage owner for having his car there and the owner ends up against a pole,

There is another scene in an old diner with two guys. Another scene with two guys driving an old car out and getting together on a blanket while the car is stolen.

If anyone can come up with the title or some way to find it I'd really appreciate it.
