You'll be pleased to hear that there's a huge variety of both economy and luxury rentals in Baerum. What you go with is largely dependent on what you're willing to spend and the activities you've got planned. Specialty vehicles offer unparalleled mod cons and comfort. If you feel like splashing out, why not book a fully kitted-out SUV, or perhaps a fancy medium-sized sedan? On the other hand, if you just need a set of wheels to get from A to B at the cheapest price possible, stick with a versatile compact vehicle (or something else that won't burn a hole in your pocket).
