Lots of views on eBay and carandclassic, but so far the only offers are:
1. swap for a Porsche 944 in a tomato soup colour. Nice enough, but not my bag!
2. PX for a 2000 Honda Civic plus some (not enough) money.
eBay yay!
Things may pick up as thoughts turn to spring and post lockdown jollies, but Betas are probably still a hard sell outside Lancia World because of all the pub mythology and Clarkson nonsense. I might give the car a whirl with The Market, who charge 5% IIRC. It has matching posh tyres so ticks their boxes.
