Silver G35 coupe suggestions?
 

I have a 06 6MT silver coupe. I've kept it it in pretty good condition, and it only has 75k kms (less than 50k miles).

I'm looking for some suggestions in terms of upgrades. I attached a few pictures of it. I was thinking of lowering it slightly but keep in mind I'm in Canada and the winters are horrendous on the east coast so I can't have it too low. I hardly drive in the winter but practicality is more important than aesthetics when it comes to the car.

The only issue that I've had with this car is the motor for the driver window just went out on me. Do you guys know a cheap place I can source the window motor?

Are there any performance upgrades you guys would suggest for a coupe with that mileage? I'm thinking of lowering it slightly, and investing in some kick *** rims a little later.

No pics, but source a regulator on eBay for so cheap.

I'm in Quebec, I have used Rock Auto for most parts, very quick delivery and all prices include shipping duty/brokerage. Try and order a bunch of other stuff you will need soon such as filters, rotors, pads that ship from the same warehouse to keep shipping costs reasonable.
