I get it a lot. I can't even carry a normal conversation about cars without hearing something similar... I saw an old friend the other day who had a pretty nice charger a few years back, so I asked him what he was driving these days. He was like "Same shit, we can't all have a BMW you know". He was kidding, but I do know what you mean.
But I don't come at them the way you seem to. I couldn't care less what someone does with their own car... it's theirs, not mine. Dude likes his car, let him like his car.
