Doesn't bother me.
When I purchased my S2000 back in 1999, I got that question a lot. (Usually right after I was asked if its a Porsche.) I'd just tell them what the MSRP was.
Lately I've been chatting with the neighbors a lot about how much their landscaping cost, trying to figure out a good company to go with. (It's a new development, the houses only have dirt lots right now.)
