No smoking. Any evidence of smoking (including smell) and the renter will be assessed an automatic $300 fine in my sole discretion. I am very laid back but someone smoked in one of my cars and it lasted for a very, very long time (and please, please don't think that putting in 10 air fresheners is going to make a difference).
Premium gas only and will ask that receipts are left in the car when dropped off.
No eating or pets either and please just respect the fact that this car is owned by a person, not a company. I will go out of my way to make your experience a fantastic one but expect the same from renters and that they will adhere to these guidelines.
