I work for a car and truck rental place right now. But it’s a small family owned one - Not one of the big ones like Hertz or anything… But we do things the same way.
It’s all pretty good advice in here. The walk-around thing isn’t too big. The people (like myself) who do the walk arounds also usually clean the cars as well, so they generally have a very good idea of the condition of the car. As long as there’s no real damage (a stone chip’s not going to matter much) you’re not going to get charged for it (Don’t forget, they take ‘normal wear and tear’ under consideration. Just don’t hit anything (or get hit by something) and you’ll be fine.
Always, always fill the tank. We charge $1.50/litre (CDN) for regular gasoline… Which is not quite double what it is at the gas station down the road. Plus it makes the employee’s life easier. Best thing is when you come in, tell them that it’s full, and write down the mileage.
Keep the car relatively clean… Normal dirt is fine, but if you’re using the car as a rolling restaurant, it’s ok to leave like a bag of garbage, but if it’s strewn throughout the car, it’s not appreciated, and you may get charged a cleaning fee… And cursed by the guys cleaing the car (I’ve found hunks of hamburgers along with thousands of candy wrappers… all in one car. Not cool.) But don’t worry too much about it… Try to remember you’re in someone else’s car, and while a little mess is expected, don’t leave too much. I’ve spent hours cleaning a single car after an extremely messy customer had it for a day. I’ve spent an entire day on a single cargo van because they wre moving cement, bothin blocks and bags, and allowed the entire inside (black rubberized interior) of the vehicle to become coated in cement dust… Rendering water and most cleaners useless, and frustrating the hell out of me. It took me personally more than 5 washes of the entire interior, and despite my best efforts, and the efforts of others, it was still not pretty by the end of the week… When we discovered the secret is large amounts of ArmorAll, which doesn’t remove the dust, it just makes it blend in with the interior.
Sorry for the rant… I just got home from there, and I’ve had a very, very bad day.
About the insurance. I believe only “gold” credit cards will cover rental car insurance. It’s best to check with your credit card company before you do it. The best option is to check your current insurance, and see if will extend coverage to a rental. Most of the cheaper policies won’t allow it, and some may only cover it if the current vehicle is not on the road (after an accident, etc). That’ll generally save a hunk of change.
That’s about it. It’s really not rocket science. The car company’s not going to screw you, especially if you mention you’ll be renting again in the near future (even if you’re not) because the rental industry survives on repeat customers. Oh, and don’t be afraid to ask questions when you’re making the agreement, they’ll explain it to you.
