I bought a German car new once and the experience was...mixed.
Car: 2001 Audi S4 biturbo
The Good: The dealership was amazing! Awesome sales staff that knew *everything* about their cars and they didn't pull any of the usual sleazy sales tactics. As well, the service department people were great, too, but more on that in the minute. The car was *tight*. Build quality / fit & finish were beyond excellent and the car was ergonomically perfect. After putting in a new ECM chip, it was good for 373hp and low 13's at the drag strip. It handled like nobodies business and the Audi Quattro system saved my butt more than once on slick/icy roads.
The Bad: Expensive and the dealership would NOT come down on the price at all. These cars were rare enough that they demanded (and got) MSRP for every one. Also, service visits after the 36k warranty was out were very pricey. And, back during this time, Audi resale values were pretty bad.
The Ugly: The manufacturer of the turbos (KKK) sent a huge batch of units to Audi with restricted channels for the coolant oil so one of mine failed at about the 40k mark. Since it was outside the warranty period, it was a $3,000+ repair. The problem with the turbos was not yet identified so the next pair also had the same defect. It wasn't until one of these failed about 10k later that I finally heard from a third party that Audi received and was still selling this bad batch of turbos. Audi never did acknowledge the problem but, thankfully, I found a repair guy that replaced this set with yet another good set for only $2,200 or so. I sold the car as quick as I could after that, not knowing if I'd finally gotten a good set or not. I wasn't going to take that chance.
