it just doesn't feel like a £100K car when you sit in the cabin
Yup.
Of course I've been driving the only, realistic, 200-mile range, fast-chargeable, EV that existed 2 years ago ... at which time I had a choice of one, so only a rose-tinted view.
And I've had some niggles that Tesla have not been able to fix (not the roadside-breakdown variety; cold-feet [suddenly, after say 60 minutes drive] and static on FM radio. I don't expect those on a 100K car ... nor for them to remain unresolved)
... but Tesla have fixed some things, gratis, that I would have expected to pay for. Cracked-windscreen (no sign of a stone chip, so they happily said it must be manufacturing fault) and they sent a driver with my wallet and house keys two hours to my home when I stupidly left them in the car [in for service].
OTA delivered all sorts of updates to me in that time, including Summon, Auto Park and Chill etc. and a bunch of refinements to Autopilot, Main Screen, and recently better maps and navigation. (also including, as the result of a discovery that they got a radar "return" from the car two-in-front, that my car will now do AEB before the Driver in front has even realised he is about to crash into the car in front of him ...)
So what would I buy today?
300+ mile battery then I would not be concerned about road-trip charging, so would choose anything that looked like it would not be a lemon.
Less than 300 mile battery then the only one for me is Tesla because of Superchargers. Even if CCS has a huge expansion program its going to be catch-up for the next two years, by which time I'd be looking to change anyway.
Other than that: Tesla has very low battery degradation (it might well be on a par with the loss of efficiency of an ICE, for same mileage). I love driving the Tesla (and now hate driving any ICE); but maybe I would love driving any other EV just as much?
Autopilot means I arrive SO MUCH MORE RELAXED than ICE days. Maybe similar exists on other Marques? I posted in another thread today, so you may have seen it, but my local A-road is rural, and not what you would call a "major aerial highway". At the moment it has temporary speed limit signs and my Ap1 will slow down for them, and speed up on exit, and [slow down for and] take a very sharp double bend, all with hands off wheel (but I always have one hand on wheel on AP, except for this passenger scaring/impressing demo)
I'm not fastidious about build quality and refinement, but I can understand how anyone who is would find Tesla fit & finish "wanting". But if the only gripe is that "Its not up to £100K standard", as distinct from "Not good enough for MY standards", then perhaps put that to one side and buy if you want any of the Tesla USPs - Supercharger, big screen, long range, hyper-acceleration, the amount of DEV that results in the OTA updates, getting young children into the rear seats (Model-X) without putting your back out ...
but more than anything, the fact that Tesla understand EV engineering probably better than any other. I would be seriously worried that e.g. a Jag will charge slowly, or taper [on fast charge] "much earlier than Tesla" (as seems to be the case from the few anecdotes I've read), or some other "version-one EV" problem
Even new Leaf, which should be mature-tech by now, has poor battery management cooling (not to mention Rapid-Gate) and still no significant big-battery option in 2018 model - maybe as a mega-corp Nisan soft pedalled the R&D once they got to market? They've certainly sold plenty of them ...
If Jag has a runaway success (and I don't see why they wouldn't - lots of innovation to fall in love with, and they are first-to-market of the rest of the pack) I can't see them making more than 20,000 units p.a. because they won't be able to get any more batteries. Unless they buy them from Tesla perhaps?
So if buying tomorrow I would want a proven generation-two manufacture, not a generation-one, with a widespread Fast Charge network.
Sorry, appears to still only be a choice of one Marque
