Tire Update:
My M3 came with Michelin MXM4 tires, I suspected that they're the weakest link and couldn't wait to replace them as they seemed to give up during high speed cornering. Recently I noticed they started to lose grip during wet weather, so time for them to go! Just replaced them with Michelin Pilot 4S, a summer performance tire I've used with BMW's and been very happy with - In addition it gets highly rated at Tire Rack and other websites. First impression was a slight increase in road noise, the Tesla MXM4 version has sound deadening foam, but the handling has dramatically improved - it feels much safer and has much better grip on fast corners.
FSD Update:
I paid $7k for this, and wished I hadn't - it's unreliable and unsafe, it's like driving with my ex-wife when she's pissed! Anyone thinking of investing in it I would wait until it's proven before throwing money at it, like all IT projects the promise is it's going to be up and running tomorrow and tomorrow never comes.
One year for ownership:
Still love it, it's quiet, fun to drive, no more gas station visits, Supercharging network is reliable and quick, stereo is amazing (less background noise also helps)....the problem is I'm now spoilt, I can't go back to an ICE ever again!
