I live in the East Bay Area and there are at least 6 Porsche dealerships and 6 Audi dealerships within 60 miles, honestly probably more but I don't want to get into counting them all. There is an obscenely high concentration of Audis in the bay area, especially Marin and San Jose, and a good majority of them are diesels. I know they are not common in most of the rest of the country, but they are very common all the way between SF and Tahoe. Probably twice as many q7 TDI as there are touareg TDI around here. These are people who routinely pay 5x what the typical jetta buyer pays for a new car, and they typically do it more often. These are very lucrative customers who have had a 75k+ car that has a stop sell on it for nearly 5 months. These customers expect a certain level of quality assurance for their insane price tags. Now they have a car that they can not trade in or even buy if they wanted to? Spending 75k on a car that is now lumped in with the 20k jettas? That is embarassing, and maddening to say the least when you have paid an obscene amount of money for a sedan or SUV. I really think the Audi thing is a bigger issue than people are admitting. A good portion of Audi sales in the bay area were TDI.
