There was a firm In Poland or might even have been Russia I can't remember now but anyway they used Volvo as the donor for Uncle Ron's Locost as it's a live axle rear end.
Can't remember the last time I saw a Sierra but MX5's lurk on every street corner her in Cornwall, some are nice condition but most are complete sheds as folk down here are too dreckly to do anything. In fact I'm sure "work" is a swear word down here.......
