Possible but pushing it a bit. Just did some anorak-type research ?The 'Campaign' model was available from August 1983 (A reg) until just into 1984. So a mk1 will not be on a B plate but it could be a very last of the line model that was registered at the start of 1984.If Keith's is a mk1 it is going to look like this:http://www.golfgti.co.uk/pageimages/mk1_red_campaign.jpgjv
If it is a mk 1...you might like to read this...the history of the mk1 gtihttp://thebody.dnsalias.org/~daniel/bigshare/VW_Study.pdfIn fact... you might want to read it anyway...pretty interesting!
Probably a Mk1. 1984 must be close to the change over, I haven't seen any 'A' reg mk2's only B reg onwards. If you post some pics we could tell you for sure.
Ok its confirmed its an early Mk2. Keith sent me the pictures this morning. First effort at posting pics, hope this works:-
