My bet would be on no, not worth it. Extra maintenance and depreciation would probably be the killer. Don't forget the hike to your insurance as you are now using your car for business purposes. It would need an accountant to go over it to make sure however. if the $150 a week you would get would cover ALL of your maintenance, fuel, extra insurance and depreciation it would be worth it but I doubt that would happen.
Please note that this does not constitute real financial advise. Go talk to an accountant
