I can imagine, you only want to go once and get it right, and not have them say "no" and take your plates away, making further test driving impossible.
The only reason I'd do it as quickly as possible, is because we pay a lot of tax each month, and electric cars are (for now) not taxed. A pretty good saving, that makes the conversion a little more wallet-friendly to run.
Please.
I'm quite curious how it will go.
