Maybe you're very tall, or very wide. Maybe you just like the idea of having lots of space to spread out as you pilot your vehicle. Whatever the reason, the amount of room available for those seated up front is important to you as you pick your new car. With your needs in mind, we've compiled a list of the 10 cars with the most driver and front-passenger space for 2006, based on the amount of head-, hip- and legroom available for those who eschew the backseat. A test-drive is obviously the best way to see if your potential new car is a fit, but this list could help you slim your search. (All measurements are in inches.)
