for daily driving, the 7 isnt that great on gas, but if u want 13's then the 7 already does it stock. about the apex seals and turbos make sure u get a 7 thats been taken care of with a healthy engine or buy one wit a blown engine for cheap and put in a new engine and take care of that. about the heat under the hood a simple down-pipe takes care of that plus a nice 20HP gain. and a nice vented hood should keep temps down.

about the GSX, no clue, very heavy almost 3500lbs and wit 210HP and AWD thats about it, though cheaper will not run 13's without a bunch of mods. and i dont really know that much about the platform anyways.

the supra, overrrated. yea its a good car, but it takes chunks out of ur wallet, if u can buy it the mods are gonna take a long time unless u got the money to spend on it. the suspension isnt all that great too.

hope i helped
