Nice idea, but only if you fancy a nice big project. Just lease a EV as a main car. I think EV's are bloody brilliant for short trips and when I dont need to carry lots of stuff. When I did the maths a few years ago it blew any diesel/petrol car I wanted into the weeds after 10-12k pa miles.
So....
We got rid of my L200 and my wifes EB Mustang last year and leased a Merc EQA which has been amazing for most of our driving, and three years time we can chose to walk away. If you are careful we get 290 in the summer and about 230 in the winter. I can get from KT7 to Dorset coast (Mother-in-laws), or my Dads nr Bath sometimes on one charge, sometimes we need to stop for a coffee (no big deal).
What it isnt is a bike and camping fun bus. I bought my first VW van this Feb. Its a one business owner slightly dented BiTDI Caravelle 4motion. I have loved working on it and using it for bike/camping trips. I thinking holidays plus other milages it will do 4-6k pa.
This was going to be a 18m experiment. I was thinking when my L200 loan finishes in a year I would buy a much newer one. I am not so sure now...
My thoughts are I might stick a new engine in this one costing £10k. Madness you all shout, £10k on a van that a 135k dented old bus, but hear me out. I know its not going to increase the value, but if I buy a say £45k van I will probably end up with the same issues. I want 4motion. I can see all the other 204 BiTDI's now going the same way of the 180's, so I could spend £45k and have the same issues and then in a few years time they are all outlawed where I live and beyond?? Maybe??
Spend £10 more on my mega straight and in amazing condition underneath bus is possibly the cheaper option, or course drive the EV as much as we can, and only use the van for the odd 2nd car requirements and bigger family stuff. I think this is a perfect setup. Obv's money no object I would do the same with a 204 t6.
