I was at a Ford dealer (Black Mountain Ford) in NC and saw a Shelby GT (not a GT500) with a gas guzzler label on it. The label said there was a $1000 tax since it was a "gas guzzler". I thought only the GT500 was considered for the tax. The GT uses the same engine as the standard GT with only a few mods, right?

Yep, and those few mods push it below the threshold for the GGT. Gonna get worse for 08 as the rules for measuring fuel economy have gotten more strict.

 

Those changes calculating the window sticker are not the same ones used for determining the GGT.

I say it would probably get a couple more mpg with the tune.

 

My 07 GT gets 19 mpg with mixed city/highway driving (optional 3.55s w/ TR-3650) and I just broke 500 miles, so there is room for improvement as it breaks in. I use the A/C a lot, but I shift at or below 2000 RPM and rarely go above 3000 RPM.

If the GT is a gas guzzler, then my Crown Vic is a gas wh*re because it gets 13-14 mpg in the city and 15-16 mpg with mixed driving. The lowest gas mileage I have gotten was 9-10 mpg using Sunoco 94 octane gas in Troy, MI.

I guess everything in Troy, MI is expensive!!
