It might have changed, but I remember ads from dealers on just the LA side of the LA-San Bernardino county line advertising that sales tax was based on the purchaser's address. That was still the case in 2014 according to the L.A. Times [1]: >There’s no advantage, in terms of sales tax, on where you go to buy a car. An Orange County resident who buys a car in Santa Monica will stay pay the Orange County sales tax rate. The sales tax rate is charged based on where the car will be registered. I suspect that the Car and Driver article was poorly researched and factually incorrect.
