I have a G35 Coupe, with 130k miles on it. Everything seems to be great, but I would like to make sure everything is running tip top. Ive been to a few Auto guys, who basically give her the once over and say everything is fine!! Does anyone have ideas to keep her at top performance?

If your G35 is running well with your mileage I'd just make sure you swap out all fluids every 30K miles and do oil/filter changes every 3K, obviously you've done a good job thus far....

regular maintaince is all she needed

Check your hoses and belts for cracks, which I assume was done. Other than that, regular oil changes and general maintenance at regular invervals should be fine.

Thanks Guys, Im happy to hear that, I try to keep her in great condition, esp with all the miles!! I put all those miles on there tho, mainly highway. Twarsop, yea i try to check belts and hoses myself but i honestly am not sure what Im checking or where.. haha I have some great/sad stories about the car.. I had to have it re- painted (crazy woman) she made a Picasso out of my beautiful G with a key.. (i will track down the pics, should be entertaining) So i had it repainted, (on her dime) but i have such road rash on the front of the car now. (highway) I want to get everything buffed out and the rims re polished.. Any ideas on how much that should cost?

It's good to know that these cars will run in the mid/high 100's if they're taken care of properly. My 2003 currently has 86.3k and I intend on keeping it until 150k (at least five years for me).

Buff, polish, and wax shouldn't be more than $100-$130 if you want to have a detail shop do it for you, and that'd be for the entire car. They can probably refinish your rims also depending on how bad they are, or you can try Mother's Wheel Polish and some elbow grease to do it yourself.

what you guys think its good to do synthetic oil with that many miles or just stick with the reg oil?

Most people, including myself, run synthetic only anyway.

synthetic all the way!
