Issue with the Volvo build is that the original engine and gearbox have been removed and they make up a major part of the front end vehicle structure where collision force is transmitted back through the chassis courtesy of the engine and gearbox. Now, there's just a great big hole and some "tin" welded to the bulkhead so I wouldn't fancy a prang in that one either. I guess the moral of the story is they're best left alone. I doubt you could even get a thing like those insured over here, some companies won't touch a car which has been modified in any way.
