For me it was a female coworker complimenting my Q50 Redsport. Interned at a 3 letter fed agency last summer and one of the other interns who I became friendly with was a mid 20’s former sorority girl - someone you’d never expect to be a car enthusiast. Gave her a ride after work one day since her car was in the shop and immediately after walking up to my car in the garage, started complimenting it. Talked about the VR30TT engine and asked me if the turbos were giving me any trouble, then talked a little shit about how it’s still slower than her car. I asked her what she drove and she had an M2 lol
Back before I got really busy with work and time did it’s thing to the paint, I had someone pull up next to me in my Trans Am - non-restored, well taken care off - and tell me it looked like it just came off the showroom floor.
At the time it was just over 25 years old. Original everything.
Damn the Van Nuys GM plant and their crappy paint. At least it lasted that long.
