In the UK there are sites like "we buy any car / Bike"
Are there any similar sites here in Switzerland ?

I'm not aware of any websites like that but there are always so many small companies offering a quick cash purchase of a vehicle. They often leave business cards on your windscreen when you park in car parks. They'll probably not give you an amazing price but if your looking for a quick sale it'll work, if you have more time try advertising on tutti or autoscout etc

Probably works for cars that you would accept 100-1000 for, most go for export if they leave a business card.

Here are some

I'm afraid I haven't dealt with any of them personally, so I'd check them out first if you're planning to go that way.

But a word of warning - I got a quote from a UK company for an old car and was quoted £450. I sold if privately for £1,500. Just saying.

I've used the term "wir kaufen autos" to find the links above. There are lots more that come up.

Thanks, much appreciated,
have the Triumph Tiger advertised on Tutti, but up to now has just been timewasters,
not the best time of year to sell, will try the links, may end up taking to the UK

Ah- clever that you never know someone might be interested here. Such a shame when people join so late, just before leaving- but hey ho. Good luck.
