My outlaws live in Malta, which, judging by the pictures in this thread, have very similar attitudes to Greece with old cars.
As they drive on the left they only get cars destined for the UK, Japan or Australasia. Due to very expensive duties on new cars, they import a lot of old stuff from New Zealand, Japan and the odd UK ones. Used cars are VERY expensive over there.
My FIL bought an Astra from us a few years ago, found someone who took it on a big transporter by road to Malta, along with around 7 other cars. As he paid us the going rate here for the car, even paying for transport, import duties in Malta and reg fees, it worked out around 1,500 euros cheaper than buying the same car there.
