After 6 years and 110,000 miles with my 2002 Protege5, I'm looking for a 2006-2007 Mazda3. I prefer to get the Grand Touring package for the interior goodies, but are there any external visual differences between the two trim levels?

 

Factory LED tails are probably the most obvious. HID projectors? Other than that, no, none that I can think of. GT"s are mostly about the amenities on the inside.

 

Yup, the only external indicator are the LED tails. If you look inside then there are a couple more: HID leveler dial next to dash dimmer, leather seats, heated seat switches above ashtray to name a few.
