Lexus IS or MB C-Class or BMW 3-series?

[josephm]

but lexus is a just a toyota, whatever it does, it will never be a german luxury sedan.

1. Audi A4 TDI Quattro
2. BMW 3-series 320d
3. C-Class Petrol or CDI (any BlueEfficiency Model)

Unless Lexus transfers its HQ to Germany.?

Anyway, I'm into the BMW 3-series. Plenty of variants to choose from. Just hope there are more diesel variants. The range toppers of the 3-series are the best!
