They "restored" one of those on Rick's Restorations (please don't ban me). It looked decent afterwards but then he claimed it would sell for $5000 or some silly amount. Soon after it showed up on eBay for that and didn't sell. Then it went down and didn't sell. Finally it sold for $3500 - http://www.ebay.com/itm/Rare-MICHELIN-MA...e91&vxp=mtr
which still seems like $1000 or so too much.
