These are not particularly rare but I’ve always liked them. It would be fun to buy one of these and shoehorn my flat 2.0 six in there. It would be less displacement than most of the VW fours put in them now, it would be heavier by probably 200 pounds and it would cost a ton more to maintain. Or maybe not.
For sale on Detroit Craigslist.
