City or highway driving? If you picked the former for your upcoming vacation in Earth City, we’d suggest a fuel-efficient car such as a mini, compact, or hybrid. They’re easy on the credit card and a dream when it comes to zooming in and out of narrow lanes. If you opted for the latter, a full-size SUV will suit you better. This larger ride has loads of room to store all the equipment you need to uncover the lesser-known areas of St. Charles. Whatever you decide on, you’ll find a collection of excellent cars on CarRentals.com.
