Thanks for the kind welcome everyone.
The M3 is uhmmm, OK but I just came from nearly 3 years in an F10 M5 as a daily so that's a tough act to follow. The M5 was epic in every way but I just didn't fancy another one, so thought I'd give the 3 a go. It's a good car and feels a lot smaller and lighter than the F10 but doesn't have that feeling of invincibility you get with the M5. Anyone that's driven an F10 will know what I'm on about! M3 is plenty fast enough and great in the dry but feels a bit twitchy in the wet and the sound is a bit "take it or leave it". I'll give it a year and see how it goes. It's a good car by any standard but I don't love it like I did the M5, even though it's obviously lighter and more nimble and in some ways a bit more "M". You actually also feel like a bit of a hooligan in the M3 which you never really did in the M5, it was a bit too below the radar. So, pluses and minuses for the M3 but nothing to really complain about!
Anyhow, here's my other two 911s just to complete the set.
