Most mobile set-ups I've seen here are in pick ups and other sizable vehicles, but it can be done in small cars too if you're creative. Here is what I have in my 2013 Ford Fiesta - a Kenwood TM-281A for 2 meter mobile work, and a Radio Shack Pro-652 scanner for public service monitoring when I'm driving across the state. Some people want a powerful sound system with massive woofers in their cars, but me? Nah... I want my radios!
