Thinking about moving on to a 4G TL or another Corvette. I have an 08 Tech, Carbon Bronze/Parchment, currently at 69K miles, is a CPO car with existing warranty until 8/2015 or 100K. I bought this car around 14 months ago, had 41K on it, but I commute 110 miles round trip daily, mostly highway. The plan was to drive it for 1-1.5 years and flip to something else before the miles got too out of the norm. Has some minor stuff as you would expect, but overall is in very good condition. Well maintained and detailed reguarly. My local dealer offered me $16K for on trade for an overpriced 09 TL Tech. Auction prices seem to be around $17500-18500 for Tech cars with +/- 10K miles. If I sell it outright, what should the asking price be?

With those miles, I would say around 18-$19,000 would be a good place to start. If you can get the dealer to go to 17k, I would say it's a good trade in.
