The Panda which was the Yugo here.
Errrrr... nope! Entirely different car, although they're both boxy looking. If it was the same car, there wouldn't be any vintage Pandas left. Haven't seen a Yugo 45 in 10 years I think!
Nowadays the Zastava factory who built these things (and got bombed by the NATO) is producing the previous model Fiat Punto, so this car is still sold (I read above that it supposedly was cancelled).
First they licensed the car, unimaginatively called it 'Zastava 10', but Fiat has decided to just call it what it is. Probably to counter act on the Renault/Dacia cheap-mobiles that are coming out of east Europe (Dacia - now under control of Renault - is building cheap cars which are sold as Renault in some markets).
Back to the subject: I love Fiat 500's - big and small (old and new). They look so damn cute! Even a straight guy like me can't help it to love them...
But actually the 500 is just a 2 door Panda (no, not that 30 year old model mentioned above!) and a close cousin of the Ford Ka, which is a reskinned 500 (with added rear anti-roll bar). Yes, all three come off the same assembly line (in Poland).
