If the aggressive advertising on the site (which is hanging up my computer as I write) doesn't drive you mad, you may be interested in this 1970 Europa into which someone has slotted a Buick stroker and Porker cogbox

Here's another

Also a 1970 car, quite a coincidence.
Well I was going to post a link to where that first car is on sale, but I really can't be bothered to log into Barnfinds again and hope their advertising doesn't hang me up. Ebay UK had this aggressive advertising for a while, now I guess enough people complained to make them remove it.
Anyway, it looks a pretty good car.
