I've only had mine a few months and so far I have gotten:
1. I was telling a co-worker that I got an FJ Cruiser as my new ride. He says, "Is that the one that...?" and starts describing the PT Cruiser
2. I was at a U-Haul yard and the guy who worked there asked me as we were hooking up a trailer to the FJ: "What makes someone buy a vehicle like this? Is it like an SUV? Family friendly?"
I just told him that it was because of its awesomeness.
Anyway, what kind of stuff have you heard? Fortunately, I've gotten a lot more compliments than insults...
