It is, I guess my main point was that $10k for a whole company isn't much to get excited about or to expect you carry much sway.
You really got me thinking about how many miles a rental car company would deem abusive. I wonder how they cost a car in terms of lost value? Obviously this isn't linear but let's say $.15/mile? So if you really do 300mi/day the car would loose $45 in value? Seems plausible. So tack on other overhead, financing costs/staff/taxes they would probably need to charge $65 (inclusive of all taxes) just to break even?
