People getting defensive at car shows!

The first car show I took my Duster to, there was a guy giving me sh*t for having a Chevy alternator in my car. I thought it was hilarious because out of all the things “unoriginal” on my car, which is basically everything at this point, that’s what he didn’t like.
Also, his “original” car was brought in on a trailer and had to be pushed to its spot because it didn’t run.
