Ref the Zastava enquiry,,,, I had one up to about 5 years ago ( i did chauffeur the current ICR chairman about in it on the saturday run to the midland railway museum.... was this from Southwell racecourse? )
The problems with registering mine;
It had no import papers as it was bought over by an Army captian from the former Yugoslavia,,, he didn't have to stop at Dover customs .
It had no documentation or number plates.i worked out it was a 1982 model, as it had plastic hubcaps and an Alternator.
I emailed the Zastava works for year of manufacture information ,They didn't reply ,hardly surprising as the RAF had flattened 75% of the factory during the Bosnian conflict ,not sure if the Yugo 45's being made at the time were WMD,they were a dodgy driver though.
I ended up paying the customs the VAT on my receipt from the Army captain,,,about 35 quid ,and ended up with a Q plate.DVLA man came and had a chat as he needed to inspect it ,That was when he travelled to you.
(Incidentally i was offered an old logbook for a Fiat 600D , but wanted to keep it genuine.)
Bit of good news,,, parts are very cheap,its a bit of a game getting them from Bosnia ,how about a set of 4 wheel cylinders, a master cylinder and 4 flexi brake pipes for £22.00... Water pump was from Middle Barton Garage in Oxfordshire,they know what Fiat 600 parts will fit.
