There's a 240 not far from us that goes a bit like that, AFAIK it's got a massive turboed (truck turbo i reckon) redblock engine in it. They have a little car meet up every month in town and he turns up there most times.
The scariest stuff is the prototypes you get driving round, missus had one for a while, ratty old Opel Vectra estate, mostly held together with duct tape, bad welds and wood screws.
3 litre twin turbo and 4wd. 350bhp and 0-60 in about 6 seconds........... (the production car was significantly slower!)
And we've got a few interesting ones driving round here as well.
