kinda crazy to see these cars priced at same levels where i bought it 4years ago. thought about changing but just dont know what car I could get that would give me the same brutal experience as ive never had a non v8 car. Anything worth getting in to after this would cost minimum 150k and i cant do that right now so i guess i just stick with this for now

113,000 currently. Purchased at 76k
only mod.. BMS Intakes

Pretty much done all preventive/regular maintenance which includes the following:
spark plugs, coil packs, all drive belts and all tensioners. Battery, aux battery, transmission flush/filter change, differential fluid change, full brakes & rotors replacement.
so far zero leaks, transmission was having that jerking/stuttering issue when I bought it but went away after a full transmission fluid flush. The fluid was green and nasty rather than blue.
car has seen 4 track days so far and has been performing well.
Update:
replacing intake magnet adjuster (aka control valve solenoid) on bank 2. 116,000 miles now
also, fuel pump issue during hot day at track w/ low fuel. I don't think our gas tanks have baffles like M cars do:/

enjoy man. Oh and be sure to change your oil sooner than the recommended 10k, I change mine every 5k and every time before a track day.

I will check next time im in at the dealer for a service what has been done and what not of the things you mention.
Apart from that is the engine bay very clean. I check and wash it regularly
