Comparison Review

Convenience
With the Mercedes-Benz SL 450 you will definitely be making fewer stops at the gas station than with the Porsche 911, due to its larger tank size and better fuel economy.

Cost
There are a lot of factors to consider when calculating the overall cost of a vehicle. The main consideration is Manufacturer's Suggested Retail Price (MSRP). Based on MSRP, the Mercedes-Benz SL 450 is clearly a better financial choice over the Porsche 911. Another consideration is the Destination Charge, which is a standard charge for transporting the vehicle to the dealer from where it's built. The Mercedes-Benz SL 450 carries a much lower Destination Charge than the Porsche 911.

Dimensions
The Mercedes-Benz SL 450 is a little wider than the Porsche 911, so getting in and out of the car in a crowded parking lot may be a little more of a squeeze. For some people, bigger is better. If that's the case for you, then you'll be happier with the Mercedes-Benz SL 450, which is slightly longer than the Porsche 911.

Drivetrain
With somewhat higher torque, the engine of the Mercedes-Benz SL 450 transmits a bit more power to the wheels than the Porsche 911.

Handling
The Mercedes-Benz SL 450 has about the same turning radius as the Porsche 911, allowing equal maneuverability in and out of tight spots.

Performance
The Mercedes-Benz SL 450 has less horsepower than the Porsche 911, so it will probably be somewhat slower.

Utility
The Mercedes-Benz SL 450 has less seating than the Porsche 911, making the Porsche 911 the better choice if you need to chauffeur many passengers.

Warranty
The Mercedes-Benz SL 450 comes with essentially the same basic warranty as the Porsche 911.
