Seems like something that either is commission based, or allows overtime.
I'll say it should be enough if there aren't any other bills.
It depends on priorities. I'm not sure if you've already bought the car, leasing, financing, etc... If financing, I have no idea amount financed, etc...
If using warranty, the maintenance isn't much per year (about $2k, including partial tire/brakes, fluids, etc...). First year was practically nothing, second year (for me) was about $4k (tires/front brake pads/fluids).
Insurance premiums might be a bit high, but individual to everyone (trends suggest you may be paying $200 or more per month).
