I'm officially going to be selling my car in the coming weeks. New accessory belt, new cam seals, cam tensioner seals, cam chain guides, and all the top end gaskets new this past weekend. Top end is in great condition. Does not burn any oil at all. Run on Liqui-Moly since first Stage III build and subsequent refresh.
New AMD 4" all stainless exhaust and tune, dual muffler sensibly quiet at normal driving speeds, screams like a a raped elephant when you drop your foot. Spools incredibly fast.
It recently had a front bumper respray at University Audi so ALL the paint is in amazing condition.
Jason at AMD knows the car, as does AvantGoFast here on QuattroWorld, the folks at University Audi in Seattle have done routine stuff, they can be objective.
The only thing I'd be doing if I was keeping it around is swapping engine mounts for new Stern track mounts instead of the RS4 mounts it now has.
The car gets 28mpg on the current tune in 6th at 80mph on the freeway with the Bosch Motorsport injectors if you exercise some impulse control (in city who knows).
Engine has had LiquiMoly 5/30 or 5/40 (seasonal) and changed every 3500-4000 miles religiously.
