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
I know there’s the (true) saying that women don’t care about cars but I got so much attention from the opposite sex when I had just a Panamera that I felt like king dick.
