Might be worth getting a little solar charger if the car is stood outside or a decent smart trickle charger if it’s stood in a garage with power, mine is plugged into one as we speak.I enjoy being retired.The only problem with being retired is you never get a day off lol.It is nice not to have to go out in the cold to work in the winter.
I used to leave my Smart standing idle in the winter,sometimes for 4 to 6 weeks.I did not go near it,but when i did after all that time it always started first time. I just hope my UP GTI will be as reliable.
There are new UP GTIs advertised on Autotrader and loads of nearly new,so you will still be able to buy one.
I’ve not driven again for almost 2 weeks, if I tried I reckon I could easily get away without the need to until at least Christmas or if that festive period is cancelled as suggested then maybe Easter 2021, so externally supporting the battery is a necessity for me.
