These small turbos are new, and stressed, I am not convinced by their longevity.
We've recently bought 2 Fiat 500's and despite the 900 turbo being a favourite, we've opted for the "normal" petrol 1200's. Less complex, less chance of any failure (big bills) and like Rick Thackery mentioned, they are great fun to drive, you have to use the gear stick like you were driving an old Mini, driver involvement, fun!
