Awesomlyhumble:
I pulled this from a previous post of mine when someone asked about buying a used M (they didn't specify the year) so it's not really plagiarism...
The M35 is an awesome car, with plenty of power for most, but I LOOOVE my V8, just a little bit more a fuel hog. Hey, but I can live with that for the extra power!!!
I have a 2006 M45-bought used at 41k miles, it is my daily driver and is now at 83k
I replaced my rotors and pads at about 45k miles (many complain that the OEM setup is too small for effectively stopping such a big/heavy car) , search Brakemotive kit for a more economical but effective setup
I have experienced a little of the tramlining many have described, but have the RSA crap tires that most on the forum have complained about--will be replacing those in the next few weeks or so.
I have NOT had oil consumption issues, but put in a catch can, because these motors do burn a small amount of oil.
I have NOT had the front (driver's) seat rail problem (poor weld for some which breaks and seat becomes loose)
I have NOT yet had a problem with the front wheel hubs going bad.
I LOVE my car and have done quite a bit of maintenance on it myself (much of the help from the DIYs Ilya has posted on the site: brake job, belts, oil (once--just a pain to get the plastic lower cover off 'cuz it's fastened with like 21 bolts), drain and filled transmission fluid, exchanged power steering fluid, replaced in cabin air filter, replaced the hood struts, and have done the Nav hack the old school way--cut and spliced wires (didn't use the aftermarket wire harness)
Sooo, with about 92k miles on the car now (still love this car!!!):
Have replaced the rotors and pads (just front pads were bad, but the Brakemotive kit is so cheap, I just replaced everything, plus I painted the rotor hats and the calipers black) or you could go with the Akebono big brake kit (BBK) too, which looks really noice!
Haven't changed the tires (too cheap) but they've held up well despite being the crappy RSA ones (last oil change at the dealer they were at 16/32 all 'round)
Getting barely any oil in the catch can...

Although VK motors seem to have more of this problem vs the VQ
Still no problems with the seat rail.
Had to change my passenger front wheel hub, pretty easy DIY, but broke off the wheel sensor bolt, so had to drill out a new one. Plus, it took a while to get the old hub out 'cuz that sum bich was stuck/rusted in there reallll tight.
Noticed that the black plastic coating on my LEFTmost Homelink button on the rearview mirror is flaking off.
Once had the fuel tank issue (tried to fill it up once and the gas tank nozzle kept stopping as if the tank was full--stopped trying and went back to fill it up a few days later and had no problems) has not happened ever again.
Got the accelerator pedal senor/throttle recall done and I think it's more responsive.
Other maintenance done:
Bought some breathable seat covers for the front seats (wanted to protect the leather some, but still feel the cooling and heating)
Changed my PCV valves
Changed my spark plugs
Changed my rear differential fluid
Planning on changing out my driver side headlight, got hit by a big chunk of metal thrown up by a semi and cracked it.
Good luck with your search and let us know if you decide on joining the club!!
It is an awesome car and you'll be quite pleased with it.
