Yeah, but the Alpina still aint as fast as the Brabus. And to be technical, the "M" division is only to BMW what AMG is to Merc, and the E55 AMG is as good as the M5 in most respects.
Regardless, the Brabus is faster then the Alpina anyways lol.
It makes me laugh, Andy posts up about a fantastic car that he has had the pleasure of driving over the weekend, and all you can say is a tuned Merc is better when you havent even driven any - in fact, Id be surprised if you have even driven a std E55 or 5 series...
The M5 was faster round the top gear test track, is cheaper than the E55 AMG, has a smaller engine, and IIRC correctly, everytime a manufacture brings out a hot luxury saloon, they sing its prasies - the only drawback is always the M5.
Sometimes its not about figures, its what the whole package does with them.
