36 years old - I've owned about 55 cars in the last 19 years, and one of them was an LPG Range Rover (which i loved) and one of them was an E46 330d Touring (which was a great car but didn't inspire me at all).
In amongst that lot were about 20 BMW's - all with 6 or 8 cylinders, all petrol (apart from the 330d mentioned above).
With the technology that's now out meaning that an 8 speed auto M135i can achieve 40mpg at 75mph (yes really!) and yet crack 60 in 4.5 seconds (BMW say 4.9 but it's already been magazine tested quicker) all whilst running 95 unleaded, i can't see myself buying a diesel any time soon...
Oh, and to answer the original question, i'd be having a 1M if that's allowed?
