Incidentally the other option at the moment is to go electric with a Tesla
Simon,
the Tesla is a fine EV for commuting and motorway use, it is quiet, comfortable, has a great sound system and is insanely quick, but my 14 months of ownership suggests (to me at least) that it is not a driver's car.
In my view Turbo cars need traction control to manage torque delivery: the BMW straight 6 can deliver max torque from around 1500 rpm, unchecked that is a recipe for adventure..
