... search the forum for FAZA Fiat
... I saw this very same car in Nov 2008.
The owner has it for sale - last seen on Seattle Craigslist for $4000.
1500cc engine, modified bits. Originally the owner is from southern CA; came to Seattle and stayed.
Listed as a 1975 FAZA (parts) Fiat.
Or an Abarth Rallye Replica. Depends on your mood.
But, search the forum for FAZA Fiat ... that forum discussion has more detail.
