I feel the same sometimes aswell, wether it be an MX5, an FC or SW20, they all seem enticing, maybe when my daily runs itself into the ground I will get one, until then im still saving for a 2nd skyline.
I find in the hills with my wagon, what it doesnt have power wise in the straights, it makes up in the corners cos im less worryied about crashing it and it seems less wide then the DR30 for some reason.
