"Hopefully it will settle down, Eriba prices have fluctuated in the past which has seen dealerships stop stocking them until it becomes viable again, I suppose on the up side is that the value of your Eriba will go up and it will probably be more cost effective buying from abroad."
If you buy abroad your £ is worth less. I ordered a new van from Lowdhams in June, the day after Brexit. At the time I would have needed to see a euro to £ exchange rate of about 1.3 for it to be worthwhile buying new abroad. [I found the dealer very flexible with the price]. This is not going to happen for a long time, if at all.
Prices are difficult to work out as the attractve listings you see on the likes of marktplaats [private and dealer sales] are not clear. You frequently need to add a substantial amount on to cover what is not included on a UK van.
You need a big bit of paper, a calculator and a lot of time to work out if it is beneficial.
