if i qualified for the 7500, its a no brainer buy.any car you buy in California you can count on paying about 1% of the MSRP for yearly registration...so a couple hundred dollars shouldn't be a deal breaker
they charge a little bit extra for to make up all the tax revenue they will be missing by you not buying gas anymore.
Btw, that new $2000 California CVRP rebate will help make up for it....or the $7500 federal tax credit
