Need a new motor

[Grant]

Argh, I'm stuck between a rock and a hard place here. Been looking into 350z's and I do like them. The insurance isn't much more at all, and it's quite justifiable.
I do love my 306, it's such fun to drive, but it's inevitably going to see me in trouble or wrapped round a tree. I can't afford to get points as it will f*ck up my work, so what's the point in having a car that your gonna spend loads on suspension shinies.
I drive my old mans insignia a lot, that's comfortable, not exactly a spritely drive, but I'm looking for comfort.
I think I'll have to take one for a test drive and start basing my opinion upon this.
