City or highway driving? If you picked the former for your upcoming vacation in Groton, we’d recommend a cost-effective vehicle such as a mini, compact, or hybrid. They’re easy on the credit card and fantastic at zipping in and out of tight lanes. If you opted for the latter, a four-wheel drive will better satisfy your needs. This bigger ride offers plenty of room to store all the necessities you need to uncover the lesser-known gems of Ayer. Whatever you choose, you’ll find a fleet of high quality vehicles on CarRentals.com.
