Probably the best-looking car Mercedes
has ever made. The retractable hardtop
is fabulous and should be copied by all
convertible car makers. It is however
seriously marred by two major flaws.
The engine pings as if it is running on
low-octane gas all the time. (I use
91 ). Going uphill with a passenger it
sounds like diesel sometimes. For a
car this expensive, it ought to run
much smoother than that. Spoils the
otherwise perfect ride. Mercedes
tells me they all do it, its not a
repairable item. Also, the controls are
very badly designed. You better keep
the manual with you at all times or be
a computer engineer.
