I bought my 2003 5AT Desert Platinum G35 Coupe about a year and 3 months ago and Im considering a change. This is the longest I have ever kept a car and I am about ready to move on but whats it worth?

I bought the car Certified Pre-Owned from Ramsey Infiniti (great dealership) with 62k for $22,500 with a the 4yr/100k extended warrantee. (When i went for my 1st service at INFINITI, the original owners info came up when I gave them my VIN, it was some Indian womans name from Massachussets, so all the miles probably came from there as well as the scuffs on the rims...women) They did about $2500 worth of crap in order for them to certify it (change 2 tires, coolant flush, brake pads, etc...) so I thought it wasn't a bad deal compared to the other 03 they had with 11k for about $33k and change but it was a 6MT.

I have 73k on it now, oil change regularly as well as pads and rotors changed few months ago, put clear corners, have my stock 18s, 2 new HID bulbs to match the 8000k foglight HID kit, and tinted it up. 2 rims are slightly scuffed but I bought them like that, theres like 3 scratches and 2 ridiculously small dings on the car and rock chips on bottom of the front bumper, and a scratch on the rear bumper (all came like that, I baby her)....

Whats she worth if I wanted to sell?

 

Well regardless of what you've done to the car like the pads, rotors, bulbs etc...you can't put it towards the costs of the vehicle. I'm pretty sure the previous owner couldn't tack on the $2500 it costed to certify it good to go. Looking on Kelly Blue Book, your 03' 5AT 73k miles at a "Good" condition lists at $19,855 private sale. Your best bet maybe to trade it in with your next vehicle purchase. The dealer might give you a better offer since you'd be purchasing their car.
