Considering that there’s barely any choice, you could test drive all of them. At around 4k, you have the Lexus UX300E, which isn’t very well received but an SUV, electric. You have the 308 SW Estate, which is probably the best PHEV on the scheme – drawback, doesn’t fit everyone. Physically. Some people, like me, are too tall (with too long legs) to fit properly, which leads to you not being able to see the instrument cluster in normal driving position due to a stupendously shaped steering wheel. Comes as a hatchback also, for £500 less. Don’t be deterred by the badge, the interior is well up there. Then there’s the E-C4, not my cup of tea so i don’t know much about it. Next would be the Captur PHEV, i don’t know much about it but it does look interesting – especially considering the price.
The rest, imho, is naff. Fiat 500s, low range Leafs etc.
Personally, if you fit, i’d go with the 308. It’s truly up there in quality, we quite surprised (and 225hp are nice). If you don’t, or you don’t fancy an Estate/Hatchback, my next suggestion would be the Captur. Looks good, well priced.
