Being in a large metro area you may be able to sustain a small market in ten year old and older MBs. There are so few of those cars owned by folks that will pay for professional repairs anymore. But a big city would be where it would be at.

Even though I'm pushing 60, I still plan for the future. Of course the future is ten years old atleast for the requirement of competent diagnostic communications tooling. I hope you have your end game planned as even in the big city time moves on. Automobile technology is expanding at a rate only exceeded by consumer electronics, don't get left behind.
