Rekin, my 2nd car was an MX6 (non-turbo), payed $14K for it and I never had any problems with it! Picked up insurance for $740 with rating 5 via GIO. They're a good car to learn in, as they've got a little bit of power and stick to road like glue (you can't go past 4WS) + pretty good on fuel too!
I've seen a few P-Platers driving around in them lately, they're a good build up car to getting a Skyline in my opinion.
