Look at buying 5spd 06 or 07 GT and have some Qs. Have done lots of reading and searches. My Qs. Do all GTs have the digital readout that gives gas mileage? What's the difference between a GT Deluxe and Premium? Looks like all 07s come with 3.31 axle ratio unless you order the 3.55 option? What's standard 06 GT rear axle ratio? Does the drivers seat raise and lower in both years? And lastly, do both years have a spare tire? Over the years (61 if them!)I've had 3 Corvettes, 2 Porsches, FFR Cobra replica, GTO, 3 series BMW, and how have an 06 Miata (no spare) that really is fun to drive but just too small. Is there any big diff between 06 and 07 GTs? Anything to look out for or stay away from? Thanks in advance. 


except I got the manual transmission
