Bit of an Update. Finally Picked up the M2 with the 1M. Obviously car's still new so I can't comment much yet. But I'd be an idiot expecting anything profoundly different.
But here are a few. It's much louder than 1M but I'm still wary of breaking it in properly. M2 definitely more compliant and comfortable. Unfortunately the car came with the Conti Sport Contact 3's. Which isn't a terrible tyre. But compare to pilot super sport, it's like bringing a duck to a dog fight. Thankfully I'll finish the life on these in time to try the apparently amazing PS4S. Interior, hate to say it but is Plain. Mind you it's my daily so I'm happy to be honest. And the 1M to be perfectly frank, doesn't have a stellar interior either , but it's all functional, all in great condition. Speaking of the 1M, after owning it for so long it is just the boisterous, raucous monster from day 1. It treats you how you treat it. I absolutely adore it and switching cars often today, really made me weak at the knees to see it on the road, a perspective I rarely see.
I'll attach some Cellphone pics. Do enjoy.
