Selling my daily driver 2011 Infiniti M56S. Bought it 2 years ago at 140k miles and have since done meticulous maintenance and a lot of cross-country drives. Still drives great and has been an extremely fun car to own, but I needed more space and moved onto a station wagon. Everything I've done has been documented in CarFax.
Oil & filter changes done every 3k miles with full synthetic Mobil1 and Castrol 5w-30, with very few exceptions. I recently did a Blackstone Laboratories oil test and only found higher levels of lead from some bearing wear. Air filters replaced every 12k and tires every 50k. Brand new Pirelli P Zero AS Plus 3 tires on all 4 wheels. Driveshaft recently replaced by the dealership under recall.
No rust at all on the body, but there is quite a bit of paint damage, especially on the front. Mostly rock chips, with a few small dents on the rear from hail.
All electronics work properly. Ventilated seats and A/C still blow cool, heat blows hot. Forest Air system still works, too. There are some tears on the driver's seat and armrest, and the steering wheel leather is a bit worn. Carpet is fantastic and protected by WeatherTech mats.
Mods include:
-PPE Engineering full exhaust system (I still have the OEM exhaust, will be included)
-UpRev tuned by Cajun Tuning, has Standard, Eco, and Anti-Theft maps currently (cable included for any future tuning)
-Q70 rear end conversion (all lights work)
-Escort Passport 9500ci radar/laser detector and laser shifter, very discrete and works like new
-Grom Audio VLine VL2 Android head unit with wireless Apple CarPlay and Android Auto
-TBW Performance aluminum engine and bell housing under tray
-New front lower control arms included, but not installed (bushings are going out)
Mileage is very high, but almost all highway miles. The engine is still in excellent condition, as shown by the oil test. Compression is ~240 PSI per cylinder, well within spec. This car is ready for another 100k miles, or would make an excellent donor car for your Y51 project.
