Jeep SRT8
Why? Easy. Its just a perfect all around vehicle. Its roomy, fast, and can be driven in any weather.
Sure I love lambos, Porsche's, etc. like the next guy, but I doubt I would enjoy driving it every single day of my life. I know Lambos and Ferraris have the worst blind spots ever and would suck to drive everyday. I couldn't fire up my LP640 to make a quick run to Kroger lol
