There's always going to be a lot of "Turbo or Nothing" naysayers around here, but what it comes down to is this:
Unless you're doing something seriously wrong, all skylines make great cars to drive. For the price bracket and your requirements (non turbo) you'd be hard pressed to find a better overall car.
As for importing, unless you can guarantee that those low k's are real, I'd look somewhere closer to home first.
oh, and 4 doors ftw
