Everything Has Its Price
As has been stated above, VW and Audi handling characteristics are the primary selling point for many buyers. I've been among them since the mid '80s. Between Dave and I, we've owned a 1980 Audi 4000, a 1976 Audi Fox wagon, a 1985 Audi 5000 wagon, a 1978 Audi Fox sedan (body and undercarriage were tight as a drum when handed off to Dave's daughter with 150K on it -- no other car I've ever owned comes even close), a 1988 Audi 80, a 1996 Passat GR6 wagon, a 1997 Passat GR6 wagon, and a 2006 Audi AllRoad.
All of those cars handled beautifully, and since we made weekly trips (on average) over the twisty and often treacherous (due to varying factors) four lane mountain highway to Santa Cruz, handling was top priority. When I was commuting 45 miles each way over hills in the other direction, the '97 Passat wagon made it a breeze at 65 MPH or (often) faster.
Some of these cars had their quirks, and some had expensive repairs, but maintenance and repairs on German cars have been notoriously expensive ever since they started exporting them to the U.S. You know what you're signing up for when you sign the sales contract.
We know people who have owned Japanese vehicles that rarely, if ever need anything besides routine maintenance, but we were willing to deal with repair costs in exchange for the safety and sure-footed mountain road handling that could make the difference between avoiding an accident or road hazard and ending up with both us and the car seriously maimed.
What VW has done is scandalous, but I'll bet they're only the first to get caught. The corporate world is an unscrupulous one, and integrity is a thing of the past. I think VW will survive this, but their TDIs may not.
Meanwhile, I'm hoping I'll still be driving by the time I can afford a used Tesla.
