Leather seats, navigation, car seat if needed - convertible.
I do have a 4 year old who makes a mess in the back. Pretty much guaranteed you will find some evidence... The shorter the notice of the booking, the higher probability of a slightly dirty car. But, hey, the car will still get you where you want to go, and cheap!
Please note the mileage limits, 100 miles per day.
Snow tires or chains
Please no smoking, return the car as clean as you found it, throw away all trash, and fill it up prior to returning
Worked out very well for our trip over the pass -- didn't have to use the cables but they were appreciated! As mentioned in the description of the car, keep an eye on your mileage, as going over 100 miles/day can add up!
