exowners

My SL500 and E500 S211 are coming up to 50k and 60k miles respectively, and now that the kids have left home, I'm being nagged to rationalise to one vehicle - and I fancy a mid-noughties W215 CL500 or bi-turbo CL600. Can ex-owners tell me whether it would be a mistake to go for a V12 CL600...
