If a particular model of car makes it 10 years without being renamed, reworked or replaced it’s a bit of a miracle these days. The longevity is what makes the 50th anniversary model of the Mercedes-Benz SL550 so impressive. The 2007 model of the SL Roadster will mark the fiftieth anniversary since the cars first rolled of the line and into the hearts of car lovers with the 300SL.

The 50th anniversary model will only be available in limited numbers, and it will be packed full of luxurious features. A 5.5 liter, 382 horsepower V-8 moves it down the road without too much effort, and Brake Assist, ESP and hydraulic brakes to stop when you want to stop. It has a retractable hardtop and comes in a metallic pewter color. It comes with a DVD based navigation system, a 6 disc changer and 8 speaker sound system from Bose, and Sirius satellite radio. No word on price, but if you want one head down to your dealer fast, or they’ll all be gone.
