Nice coupe. Is that an auto or manual? Werks big wheel turbo and intercooler are great mods. Don't fall for the value/investment bait. As long as you don't have an NA auto, your value should hold up very well compared to other 09 vehicles in the price range. They are very hard to find. As little demand as there is for these, NA's are abundant on all the online sales sites and are selling in the teens, while manual GXP's usually number only 2-3 for sale at any given time on the planet (or less) and still hold close to their original prices.
Hey, Bill, what's this about V8 cars being poor values? Of course, there are a lot of old, 06 Malletts out there, that have been beaten into submission with stock five speeds, etc. (ragtops), but, I believe, only 3 or 4 coupes with the well-sorted, low mileage LS3's and proper supporting hardware.
I'm getting ready to move mine, so hope it brings a bunch (going to a charity).
