Get an M5!! I would say that though even though its 3 years old, I love it to bits, I had a 2009 m3 convert just to sell on last month, was very nice to drive but the m5 felt quicker and nicer to drive, the m3 convert is more flashy which I'm not really into, absolutly love the the car, just don't like everyone staring all the time but I think that probably goes with any convertible, the m3 coupe probably wouldn't get no where near as much looks, the m5 is quite a subtle monster which is what I love about it even with the 21inch hartge rims, it still looks subtle, some people don't even realise its an M5!
I just love cars that blend in but a real monsters, also like the audi RS4, dare I mention an audi on here!

Only you can decide what car you get next! No one else!

Good luck anyway!
