2002 Lexus IS 300 SportCross 4dr Wagon (3.0L 6cyl 5A)
Just bought a black on black Sportcross and I am really enjoying it. Handles and brakes better than anything else with this much cargo flexibility (bar none). All it needs is a low pressure turbo or supercharger and it would run with an M3.
Brakes, handling, stereo and cargo room.
Don't change the engine; just add a low pressure turbo or supercharger to bump output to 280 HP and 300lbs/ft of torque at low rpm.
