Alfa 159 2.0 JTDm Lusso 6sp.
The 5.5 twin turbo or the older supercharged one? They are generally pretty reliable...they are just a w212 shape E class in a posh frock! I don't like the first generation (like in my comparison)....very odd headlights....the facelift version looks much better.....but as far as dimensions go they are the same.My dad had a CLS like that one, in 5.5 V8 form. It was fast in a straight line but it didn't handle and he had lots of issues with it. Rusty brake pipes at only 5 years old, loads of electronics faults, issues with the air suspension, window regulators...
