The Audi's are appealing, but damn, they're complex, difficult to work on chunks of high tech. My friend has a B7 S4 that's he's now worried about. The timing chain guides are plastic and have been failing on many cars. The failure is catastrophic. On that car the timing chains are on the firewall side of the engine, so repairing it is an engine-out proposition. Perhaps you're buying new so take it for what it's worth, but if you're picking up a used one, be careful. Good luck!
