It's the long term ownership experience that matters. This is where the falls down in the stealer trying to take you to the cleaners at every maintenance opportunity. I was quoted USD 15,000 for work that my independent did for USD 1,500. Reading the list of major problems from another lister I am sure his dealer is "fixing" more than he is telling you about. They make money on warranty repairs too. By contrast, the Lexus after sales care is welcoming, competent and good value. Satisfaction = car + after sales. I have never driven a 220 but I imagine it is better if you sit in the front while the 140 is better if you sit in the back. I sit in the back almost all the time. I love the 140 but would prefer a C36 for personal use.
