Further down the road?
You thinking like 20 years down the road, then?
I cannot see how ED30 will be gaining in value, ever. It's not like it's a special edition Porsche or Ferrari... And it is not THAT limited. I don't know how it is in Britain, but here in Switzerland there are tons of these cars for sale.
So what's then the point of having ED30 and not driving it?
I've done about 38000km in less then 2 years, which is more than I expected, actually. And I will continue driving it as much as before, if not more.
