The R230 SL
|
|
|
The page isn't about basketball, but I'm a Knicks fan. That said, Kobe Bryant is the best player in the game. LeBron is the best player "on his team". I like LeBron, but if LeBron and Kobe were on the same team, the ONLY reason LeBron James wouldn't be on the bench is because Kobe plays guard, and LeBron plays forward. If you need the BEST PLAYER, it's Kobe. That's the R230. Some day, a better roadster may be built. Maybe. But for right now, for two people, and not much luggage, the ONLY reason to drive something else has nothing to do with the car.
Similarly, there's one Jeremy Clarkson. There is no second place. The second best automotive journalist is not almost as good as Clarkson. The second best automotive journalist is a journalist, who happens to write about cars. A better automotive journalist may come along one day. Maybe. But until then - Clarkson. Period. BTW, Jeremy Clarkson sold his Ferrari F355. He bought an SL55.
