Reportedly "restored" in 1996 to an Alpina clone. No clue what on there is Alpina though. The car started life as a 1600 Touring, so it's possible the stated 51k miles relate to the 2ltr motor that's in there now, or just since the resto.
Was on Ebay several times during 2016 with "Buy it now" $30k, when the car was in Burbank, CA. During 2017 Rolf's Auto has had it for sale ranging from $38k to $30k.
