Been watching this baby on German eBay - the Seller was a bit coy about identifying it. I'm thinking Tatra. Looks like going for about AUD10k

could be a fiat?

I had a Toppolino once - similar but this looks larger.

This angle looks a bit familiar??

Hmm, Topalino, yours must have been different to the one I had, vents say rear engine. Still, I have no idea what this one could be.

Thanks Bruno, I can't trick the old codgers.

Interesting ....... a copycat car .....

All it needs is torana tail lights to make it fully rad

Ain't that a late 40s early 50s Mercedes ( Daimler Benz )
