I wouldn't say the GXP seats aren't much better...yes the suede does help with keeping the seats a bit cooler..the bolster are the same and yea we have the power lumbar. Any 06+ will have the same interior...or could easily be upgraded down the road. Brakes are good especially when matched with a good set of brake pads. Billsteins are obvious geared more toward comfort until you have to replace them chances are you may cheap out and go with kyb etc.
