Here's another case where I might be all wet. You can judge.

I'm guessing he knows you "hate that car" which is something he obviously loves.

If you're willing to consider it, try a different approach. Try showing interest in his car .. ask him to tell you about it, show you what he's been doing, etc. Not because you care about the car, but because you care about him. Who knows, could translate into something that brings you closer together.

May seem hard to do at first, but I suspect for a lot of us we get to feeling defensive if the one we care about seems to be attacking something near and dear to us. Definitely doesn't help the sexual side of life when that happens.

In any case, you've got my good wishes.
