You can get a used M for $40-50k. I don't think you need to be making $200k to afford that. A new Infiniti G35 will cost that much. It really depends what other expenses you have. Overall, if you can meet all expenses and still put away about 20% of your take home pay annually on top of your 401k, then I say you are okay in terms of affording a given lifestyle.
