I went for the 2.0L rather than 3.0L (the in between 2.5L made no sense to me) because it is a long term car so running costs are important. The lighter engine means this is the best handling car I have ever driven. I can blast round beds, be they sharp corners or sweepers at speeds that make my hair tingle. I used to race stock cars and have had a Morgan +8 - the Zed 4 is better. Blasted across Germany at 90-120mph and got 41 miles per gallon. I live in London and still get 30mpg. I love the looks (pre-facelift) and always stare at the car when leaving it. Driving does not get much better.
Looks, handling, miles per gallon, the power roof, everything - more smiles per gallon.
Ditch the run flats - I did and got a new car with much better ride!
