They're now quite popular in the UK, along with Jaecoo, although not a huge number of them are pure-EV. Since I have been in the market for a car recently, I've been carspotting to see what's actually on the roads, and looking out for green-flash plates. VW and Tesla seem to be the carspotting winners so far. Autocar (and other reviewers) are mad about the Renault 5, which does look extremely good. I have an Abarth(!) 600E on lease-order, which I will review for HN eventually.

It is very funny that the Seagull had to be renamed Surf because Brits hate seagulls, though.

I own a Sealion 7 since August. Build quality is much better than European brands like BMW or Audi, it really feels premium. I'm loving this car.
