Chevy dealer called and will come back back with a better offer and make it a GM certified used car which equates to 12 months 12k miles bumper to bumper, plus comprehensive inspection etc. on top of the standard 100k mile powertrain warranty. If they are willing to make a really really good deal down from their asking price, I'll have to give it more consideration.

Starting to look at the available Shelby GT500 convertibles in the eastern 1/2 of the US today. Not sure about colors, I want to see the Kona Blue in person, in one of the pictures it looked a little purple. Metallic grey with black stripes is interesting and the black with white stripes is striking but hard to keep clean.

Again, I recognize how very fortunate I am to have these kind of choices to sort out.
