And I've just passed the 18k mark in my BEV, so am on second set of tyres (the rears go first - can't think why).
As the previous post mentions, the range can be an issue if you plan to go on longer trips. When I first got my car last April, there were no DC chargers but now Ecotricity has rolled out a lot in the motorway services, it has opened up the possibilities so I regularly go beyond half of its range, i.e. have to charge away from home.
The main issue is that the reliability of the fast public charging network is not good enough yet. It is free, so far at least, but you can't rely on it the way you can a petrol station, yet.
The range is affected by weather - I think I'd say about 25% less in winter and until last week I still had the de-tuned on board charger so a medium AC charge was only at 5Kw so charging took too long. That's now sorted. Bizarrely, since it had that fitted and the associated software changes, the indicated range has shot up so for example where on a freezing January morning the car would kick off showing a sub-60 mile range (on comfort) in a coolish March morning it's now showing 80 plus. I'd say that the estimated range is now closer to what I can actually achieve whereas before it was pessimistic. On EcoPro+ in central London it doesn't seem to use any range at all.
Having said all that, it's a truly excellent bit of kit - I enjoy driving it now just as much as on day one. The brutal acceleration from slow speeds is addictive as is the silent progress, the app (heating/cooling the car remotely, checking you locked the doors), the blue glow when you unlock the doors at night, oh and the c 3p per mile cost to run.
I have a business so I contract hired mine, then I know how much it's going to cost and am not concerned with battery life or residuals. Personally I don't get the point of the Rex - but I have access to other ICE cars so if I go on a long trip I use one of them. I wouldn't yet have a BEV as a sole means of transport.
Go ahead and enjoy!
