The main instrument cluster has been redesigned, with new chronometer graphics and additional leather stitching on the binnacle. New aluminum trim panels are coordinated with a new burr walnut wood trim. New, softer leather is used on the seats and panels, and new colors, black and red, have been added.
Cockpit comfort in the SL550 as well as the other models is superior, with a huge range of seat and steering wheel adjustability, and the seats are supremely comfortable and containing. This is a two-seat sports car, however, and there's still that wall behind the seats that restricts seat travel and may make taller drivers fidget around, looking for the best compromise in seating comfort.
All of the controls are in the same places as on the 2006 model, albeit surrounding by more aluminum trim, and they're easy to use, including the COMAND system and the navigation screen.
With the steel top up, you have the kind of grand touring intimacy you want with your driving partner. In 16 seconds, you have the open-air cruising mode, and with the side windows up and the conversation panel flipped up behind the seats, you can converse with your partner in a normal voice, or listen cleanly to the stereo right up to about 100 mph when the wind noise will win out.
Sirius Satellite Radio with six months of free service has been made standard equipment on all models. The in-car hands-free communication system can use either Bluetooth connectivity (to use with your Bluetooth-compatible cell phone) or a multi-handset interface, each of which is sold separately from the car through dealerships.
An electric trunk lid opener button has been added for 2007. A power trunk lid closer will be added but won't be on early 2007 models. The luggage cover, which keeps luggage from interfering with the stowed top, is now removable, to add more luggage space in the tiny trunk. If you're planning on carrying more than a weekend's worth of luggage for two, though, you're out of space already. The SL offers 10.2 cubic feet of trunk space with the top up, 7.3 cubic feet with the top down.
The folding and disappearing power top raises or lowers in just 16 seconds.
