Just pulled up a few of my records
Replacing throttle actuator last summer: $1327.41 in parts, $738.40 labor
Head gasket replacement, screws, o-rings, self-locking collars, pulley adjustment, adjusting belt tensioners, new deflection pulley, filter, compression springs, fluids, all belts, vanos oil lines, arp bolts, be rod bearings: $1806 parts and $3850 labor+ tax ~ $6116.14
Oil and filter change ~ $275
Coolant Flush ~ $300
Final Drive Fluid Flush ~ $350
Transmission fluid flush ~ $260
SMG service with adaptation ~ $370
Replace microfilter ~ $220
OEM brake pads, discs, steel brake lines, fluid flush ~ $1417 labor, I bought all my parts somewhere else but they were like $2k for everything, and also Dinan monoballs were part of the same job, so all and all it was actually more like $4k for it, rather than 5k.
Just a little glimpse into ownership right there.
Basically, the only things which broke over the years of ownership were the actuators, some of those were like $800 bucks to replace (I think idle), and some were 2k a pop (throttle)
Other than that, the car didn't really brake down, and I just end up doing these $300 oil changes..
