The value of the car s/b about $15k as the rubber and plastic parts of the car will go brittle (aging) over 10 years. I would keep the car and have your kids, grand kids drive it.

 

If you check the prices on Cars.com the most expensive 2003 is priced at $20,488 and has 39,439 miles on the odo. The average mileage for 2003's selling for $19,000 is 45,000 to 57,000. If you check Autotrader there's a 2003 selling for $19,000 with 39,935 miles but the car has had 3 owners. It is getting very hard to find low mileage pristine stock G35's. When the G35 came out in 2002 there were no coupes that had the combination of looks and luxury and respectable performance. Coupes that would have been similar were already gone...the Supra, Mitsubishi Spyder, RX5. The G35 Coupe is the car that saved Infiniti. The popularity of the G35 to this day is testimony to it's desirability 5 years after the last model year. I say hold on to your Coupe. In years to come (5-10) it is going to become increasingly difficult to find a low mileage unmodded coupe, one owner, like new condition.

 

Thank you-- to all that --gave me some great ideas about my coupe--if I decide to part with it --I am going to ask 20K and see what comes about --if no one wants it for near that price --guess I will just keep it covered up on my garage-thanks again for all the advice

 

I just bought an 04 Coupe AT w/22k miles for $15k. That is way below book and less than the seller's asking price. I only buy when it is a car I like at a great price; like the 04 GTO w/7k miles I bought last year for <$15k.

Keep in mind that asking price on Autotrader/Cars/etc is generally higher than the selling price. In the G community values seem to be very high (these people love their cars); in the open market there are a lot of potential buyers that will skip your add when they see 03 @ $highprice because they don't note the low miles, condition, etc.

I have had good success selling on craigslist, use a good title like "2003 G35 Coupe with Xk miles"; be sure to include pics and put the price at the bottom (end) of your description.

In most cases used luxury cars are difficult to sell (people with money buy new cars); also ten year old cars are hard to finance so you need buyers with cash. The good news is that younger people love these cars and they are inclined to look for them online so craigslist should be a good venue for selling.

Good luck!
