The SL is a strict two-seater, unlike some of its similarly priced luxury convertible rivals that have limited space for two more passengers. Putting the roof down takes around 20sec from a standstill, and it's now possible to move off and travel at up to 25mph while it does so. With the top down, those inside are nicely protected from buffeting, even at speed.
The folding metal roof may protect against the elements well, but it does limit boot space when it’s folded. There’s a boot divider – a shelf that must be moved into place that restricts the 504-litre space to 364-litres before the roof can be lowered. At least the boot is big enough with the roof closed to carry a decent amount of luggage.
There are also more cubbyholes and other storage spaces in the interior than many rivals. All this adds up to make a car that you could quite happily take on a long-distance driving holiday without too much fuss.
