Test drive: 2006 Lexus GS430

The premium sport sedan market is heating up and it looks like the Germans are in trouble. Our own BJ Killeen just returned from the BMW 3-series launch and came away a bit underwhelmed.

Check out Colin's road test to see what Toyota's luxury marque has been up to... and why the Germans should be very, very afraid. -- Aaron Gold
