Cheap EV + ICE vs 1 hybrid

[Gcc1]

Advice much appreciated - currently running a 2010 BMW 330 Touring (moded ever so slightly) as a daily and a Porsche Cayman as toy. Have 3 spaniels which need to be taken to muddy walks everyday about 7-8 miles away. That job used to be done w a Vellfire but the CVT went.. Anyway dogs hate Beamer as it’s too loud, too bumpy and it’s not the most economical car especially given its age, and not really big enough. Also go down to Dorset almost every other week which is about 300 miles round trip, usually on Friday evening. So thinking of retiring the Beamer and get a cheap perhaps Mk 1 EV like Nissan Leaf as a local runaround (max budget £5k) then buy a bigger car for Dorset next or up the budget to get a hybrid which is comfortable on a long journey to do both jobs. Any advice on whether getting an early Leaf is a good idea or what hybrid to get? Do public charging point allow 3-pin charging required by older Leaf? I live in a G/F flat so if pushed can run a cable overnight out. Cheers
