Overhere a Abarth is about 25000€ a mini S about 32000€
A mini S is also a fun car but i think there are some problems with the engines
The Abarth is bulletproof and it is something different
About tests look at the TopGear YouTube clips
i don't know if i would call the abarth bulletproof, especially considering it's relatively short life span thus far.
as a MINI S owner, I can say that yes, they are finicky... but nothing proper maintenance and a keen ear can't handle.
listen to it, and it will tell you what's wrong.
not sure about europe, but here in the states we also get 3 years maintenance free, and a 5 year powertrain warranty.
mine did have some issues with the timing chain tension piston, a relatively common issue. whole timing chain system was replaced under warranty.
i'm sure people have had their fair share of issues with the multi-air motors from fiat.
