It turned out...sorta ok. The tires were shot, not because they were brittle, but because they weren't round anymore, since they were never rotated. No UV damage, since the car was inside a garage the whole time. All the fluids and belts and things were exchanged. The car passed inspection.

The repair place was incredible, since the guy whispered to me to check for parts on the internet, which I did, using their very detailed estimate as a shopping list. I ordered all (new!) parts and fluids to be send to them directly, and ended up paying about a third of their quoted prices. Total cost for parts and labor was 1300 EUR.

My brother drove the car from Germany to Spain (1900 km) without any problems, but it has since developed problems with the gear box. It's an automatic, and will often refuse to shift down, which is really annoying if you live on a hill. In addition, it will sometimes also come close to stalling at the same time. It is being driven mainly using its tiptronic now, in the hopes that all the little gear thingies will realign correctly in a little while. Also, the computer will be reset. Should all that fail, I guess it will be the shop again, but I dread the estimate my dad will face if the gearbox needs to be replaced or even just dismantled...

But the car is really beautiful again and - when it does - drives like a very smooth dream.

Here are two "before" pictures; weirdly enough, I didn't take any pictures after the repairs.

Do you think I should post a follow up? Won't I bore people to death?
