Vauxhall Insignia.

There's very little "Alfa" in there- it's almost entirely GM-badged stuff, not that it's necessarily a bad thing as you can shop around for parts between Dealers (Vauxhall EGR's are cheaper than Fiat/Alfa IIRC, despite being the same part).

159's chew through front tyres, especially with the bigger engines like the 2.4- many people were going through them in 10,000 miles/6 months!
