Selling race car, Swiss buyer - advice please?

[Mischa33]

I have serious interest in my race car (modified saloon, not road registered) from a prospective buyer who lives in Switzerland. Before I get too carried away can anyone please offer any advice with regards to the export process (which I assume is more complicated due to Brexit)? It's not a particularly expensive vehicle but depending on likely tax costs it may or may not be worth pursuing.
Any advice would be greatly appreciated. Thank you.

Hi - thanks for your answer. It hasn't got a V5 (any longer) as it's not been a road car since 1997. My preference is that they come and get it - as I no longer have a van and trailer, though I suspect a third party will be used for the transport as I don't think they have a van/trailer either. I guess there is at the very least the carnet to get into France that's a requirement?
