Enjoy it! My wife went from a 10 to an 18 and loves the new car. A spare is no big deal to us as I have stated in the past.My current car, does not have one, neither did my last and my next won't! It truly is up to you though. We still have our 10, it's our sons first car.
I bought the Toyota all weather floor mats and cargo liner from an Amazon seller as soon as I could. There are different cargo liners depending on whether or not you have the spare tire. The rubber is quite good protecting the car.
