Hi all! We're about 85% set on buying a Prius as a replacement for my wife's 2004 Pontiac Vibe. I just have a few questions. I tried a few searches but didn't see anything. 1. We live in DC which is one of the "CARB states." However, there are no dealers in DC which means we'll be buying the car in VA. Will we still qualify for the 10 year/150K mile battery warranty? 2. Do we have to get the Clean Fuel/Hybrid license plates or can we keep our regular ones? 3. Buying a hybrid in DC means not paying any sales tax but one VA dealer says there is a 0.17% VA Dealer Business tax. Has anyone heard of anything like this? Thanks in advance for everything.
