2 questions I'm looking for help with regarding a Model 3, long range premium RWD ex demonstrator.

- Are there any real concerns about buying a demo car (75 plate) with 2000 miles on the clock . I'm sure they have been booted a little but does that matter with electric motors? Any battery concerns?

- Am I right in thinking that these vehicles, will have not previously been customer registered and so will qualify for 100% First Year Allowance?

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?
