I think certain models are cool but beware of the repairs. If the hydraulic suspension fails, that whole system is crazy expensive unless you replace with a standard aftermarket setup which gets away from what makes Mercedes.
Very fair comments. Just because a car depreciates 80% does not mean that the repairs won't be 100%!
In my case the CLK has a decent reputation for reliability. The 5.0 V8 has a very good rep, it has been around a while in various cars/SUV's.
The CLK has traditional suspension vs the air ride in the E and S class, so there's at least 1 thing I never have to worry about failing and costing me tons of unexpected $.
So far it has been pretty easy stuff - new engine intake filters, new cabin air filters, new wipers, a new brake light bulb and 2 struts for the convertible partition on order. Under $500 including the mechanic's review when I bought it to ensure I knew what I was getting into.
Had a nice 60 mile top down drive today over lunch. Man that feels nice in good weather!
