Whenever I read reviews on the 2nd gen IS like this it always makes me smile. It is a brilliant car in so many ways that car journalists simply don't understand.
Ride quality, reliability, comfort, equipment, safety and build quality.
Whenever I see it parked next to a e90 3 series or a w204 c class or the early 2000s a4 it is better looking and more modern, in fact it has aged well over the years compared to them.
As with any car, colour, interior colour, wheels and spec make a big difference.
