[E30 sam]

I've owned my E90 320d M sport since August last year and I've covered 18k in that time but in my last 10 years of driving I've had some 30+ cars so as you can imagine I'm starting to get itchy feet.

There isn't anything wrong with my car & the fact I spent over 6 weeks looking for the right car which was well spec'd makes it even harder to sell up but my company don't reward sustainability and I d actually be better of driving a less economical car as I currently get 15p a mile where as over 2.0litre diesels get 18p a mile and petrols overs 2.0 litres get 25p a mile.

I would love a new 330d but having bought a new house I can't afford it so I'm thinking a Z4 coupe although I'm open to other suggestions. Anyone else get this feeling to change when there isn't really much to be gain when there car is already superb?
