I went this route about a month ago, it's not Obamanation approved but fukk em.....
G8 GXP....6.2L LS3 N/A, 6 Speed manual.....415/415....13.0 1/4 mile stock....MPG is like 14/20. It will hold a couple of car seats in the back and has a huge trunk for picking up the groceries... Nothing like hanging even with or even walking a new mustang GT or camaro ss with a 4 door sedan.
