Airsic, the C210 demands a fairly high level of respect, which unfortunately a lot of pilots don't have, especially low hour ones. The rate at which it is hired out depends on how many hours/year it does. If it does approximately 200hours/year, a break even rate will be somewhere around the $300 mark. It will be significantly less if you are prepared to work with your LAME's and get your hands dirty as a lot of the costs can involve diagnosing the hydraulic landing gear. A good reference on running costs can be found by buying the Cessna Pilots Association Cessna 210 Buyers Guide by John Frank. It has a whole lot of information on all C210 models and is a must have before buying any 210.
