rsimmons 06s are going for like 16-18 where I live. I dont know if they will drop to 10 in a year and a half. Most 04+ with average mileage are not even 10 yet. I am sure it depends on where you live, but a decently equipped LS with 60000 or less in miles is still up there in price. they have already had their big drop from 45000 in the first couple of years. Cars usually hit a point where they stop losing so much value.
But I hope you do find a good deal on one. And who knows maybe I am wrong and they will be going for 10 soon.
Yeah I should have mentioned I'm guessing I will get like 3k for mine so 13 minus 3. I looked on autotrader last week though and they had a few with 40-50k without nav for the 13's already. There is one with like 23k and loaded for 18.
Do it Lucky_Ls!
