Well these modern computer driven vehicles from any manufacturer really really WORRY ME.
In theory a manufacturer in the EU is supposed to support a vehicle for AT LEAST 10 years. F that. Fiat gave up spport for the Strada 130TC less than a year after the last model was shipped.
With the likes of the Strada and othe 19XX and possibly early 20xx model then support is a "want" and not a "requirement".
Come the 2010, 2015, and later with all these modern computer "digital configurations", rapidly week by week, month by month changes I have no confidence Fiat or any other manufacurer will "guaranteed" support you vehicle 5 years after production date. Worse still the technical, computer, technical details are "closed proprietry" information so not available.
In the old days if something mechanical broke you could fix it, bodge it, or make replacement components yourself. This avenue is not really available to owners anymore..
Whilst there are companies that can hack / reproduce modern electronic vehicle components their business are driven by commercial viability. To this read NUMBERS. Sadly Fiat in the UK is only a very very small member of the market and even less so to those that can "fix it".
Time to build a simple steam engine or get a horse or donkey for your travels!
