Our Man in Tunisia, Amine Karzai, does it AGAIN! He found this one on ebay UK! Thanks, Amine! :)
1982 BMW E21 323i Baur Convertible
Hmmmm. :) Could it be the same car?
UPDATE 4/4/2014: Kieran E. of the UK has solved the mystery above. The pic above is Kieran's Baur, and it is NOT the Baur listed on the ebay ad. Here is another pic of Kieran's car, posted in Facebook the other day. Getting some prep work done to get ready for the driving season!
Thank you for helping us get that sorted out, Kieran! :)
