I spotted that Tesla have updated their 'Vehicles Available now' Inventory today and they had an M3 AWD in the colour I preferred for collection at my local Tesla Garage. I jumped at the chance to get one quickly and clicked order. I now see on the app that the delivery date is est 18-30June. Has anyone any experience of buying from the available now and what wait time does that realistically mean?

I've bought a new M3 LR RWD. The AWD has subwoofers listed (+more speakers). I'm interested to know whether you can retro fit subwoofers in the back?
