Buffy raises both eyebrows on the subject of car-molesting, her expression fairly wry. "Well, it's a nice car." She doesn't make any further comment or ask any more questions, because Faith and Buffy have this complex relationship of trying to stab/drown each other periodically, and she'd rather not get into it.

"Who's Toby?" She asks, also pausing for beer-sippage, before almost choking on it with indignance. "My vampires are very hardcore! Crazy ancient shaman guys gave me superpowers to fight them! Or... not me specifically-- it's a heritage thing, but that's not the point. Yours are just... weird."

Yup, that's the crux of her argument right there.
