I would tend to agree with your electrician on the outlook not being in your favour. I have seen some weird wiring in my time so never say never!
Worst case is a new supply from the meter box to the garage or charger on the extension wall sorry.
Another option but, one I wouldn’t entertain is, if you have a 4mm2 cable supply to garage is to the derate the charger from 32 Amps (7,2kW) to 16 Amps (3.6kW) however it well be twice as slow as, an already slowish 7.2kW charger. Having a 3.6kW charger or a 2.3kW granny charger for aPHEV would be acceptable but, it certainly wouldn’t be something I’d recommend for an BEV. Something to think about with mrs GG.
Yes depending on your DNO, your cut-out fuse will be upgraded to 80 or 100A and most probably 80A. This work is normally free if your having a EV charger fitted or you electrician fills the form in saying you are ?
The new Tucson will have the same infotainment system seen on the new Kona, which is a massive upgrade to the one now.
I looked at the Cupra Formentor VZ2 PHEV 245 – the seats were nice being Nappa leather along with a leather covering on the dash. The overall quality was uplifted from typical Seat but, was let down with 99% of functions being touchscreen based, which I dislike. Having lived with the outgoing Tucson, I know how difficult it can be to touch a haptic button when driving let alone a fecking touchscreen ane one of reason I discounted the X1 TBH.
Infact mrs kezo and I went through the list of vehicles available on the scheme and there wasn’t one we would actually go out and buy!
