I am violating my own policy of not commenting on cars and I have no qualifications for commenting on the structure but, ????. Doesn't the lister see the Alpina connection which appears to be real? Obvious lack of effort/attention to details but you have to wonder when those seats made it into the car and the trunk specs as well. Maybe or maybe not Alpina spec'd this car a certain way. It certainly looks interesting and dare I say deserving of a thorough background check and a proper restoration?
