GXP. You'll prefer the drivetrain, the Northstar system and its 4T80E tranny can't be beat.
yea, but the North * engine is feared amongst mechanics everywhere, Series II would be the better bet in the long run cost wise.
the GXP is better in someways though, either model I'm sure you'll be happy with
check out "2000 and newer" and the "GXP N*" to find out the problems and such with both than go test drive both
If the GXP requires only regular gas get that. It will be more affordable in the long run. If it still requires premium then get the SSEi and save your cash.
the N* DOES require high octane gas just like the SSEi does
I suggest using nothing but what'* requierd for your car to run at it'* best.
