Given some cars are right now MUCH cheaper in the UK, how much cheaper would you pay for a RHD car vs a LHD car, given they would otherwise be the same, and both registered already in Switzerland?

Off the top of my head, knowing that selling it on would be harder etc, 25-305% less. It's not just the price, they are compromised in other areas , try getting a car park ticket from the drivers side, having to dash out at every toll, merging onto motorways etc... RHD's in a LHD country are compromised, the price should reflect that.

To be honest, less than it would be worth - that is, it would be better to take it to the UK and register it there. Unless it was a classic Jag or something that would be hard to get here and would be just an occasional drive.

Like Economisto, I would only be interested if it was a classic: I would not buy a RHD, whatever the price.

What she ^^^^^^^^^^^ said. Too many issues with parking ticket machines, overtaking, etc etc.
