Is Mercedes-Benz CLS 550 a good car?

the CLS is the sexy sister of the E class, they share the same platform, same chassis, same engines (new engine for 2011 which is the 4.7L for the 550 models that makes 425bhp). the CLS is new and something special, i would suggest you test drive one but i dont think its that available for test drive, since its new and very rare, go ahead and buy it, the S class is safe but its kinda old, you can get the same options on the S class for the CLS, except for that split screen options, cuz its only for the S class, not sure if they offer it on the new CLS
