2006 Nissan 350Z Coupe 2dr Coupe (3.5L 6cyl 6M)
Most Bang For the Buck
 This is my 2nd Z. My first was an 03 Enthusiast with the 5A.  I couldn't stand the car.  I had it only 6 months and sold it.  I bought my 06 last August.  It's the base model with the 6 speed manual.  This is the most fun car I've ever owned.  It's a complete 180 from the 03.  The exhaust note is amazing, gas mileage is awesome for a 300 hp car, and the reliability can't be beat.  This is my weekend car, while my 07 Audi A4 is the daily driver.  The Z gets a little bone-jarring after a while, but I always have a blast driving.
