Don't worry, you are not the only person in Australia that likes them.
I have just bought my fourth Regata that I have had in the last 15 years.
It is the very last of the line and pretty much the last of the Fiats sold in Australia when they were here before.
It is an 89 100Sie with the fuel injected 1.6 Twin Cam. It is totally original and unmodified. It has all its original documentation showing Perth delivery in 1989.
I have one or two small items to attend to before submitting it for a roadworthy inspection.
Rust has never been much of a problem on these and to be honest they don't deserve the crap reputation that they seem to have. Its no more or less of a Fiat than any other of the era and is certainly no better or worse!
Though I have to say that I have its reputation to thank for dictating the price I paid for it!
For $240.00 I don't think I can go too far wrong!
