I traded in a Mazda Tribute for the new MX-5 ... and I'm glad I did. What a fantastic little car. I find myself choosing (I shouldn't admit this!) the MX-5 over my 2005 AMG E-55 with 500HP -- the little Miata is actually more "fun" to drive (though not as fast!). SUPER JOB, Mazda!
Pure driveability. Great mileage. Intimate (several people have told me they feel "intimate" inside the little MX-5).
Absolutely none. (I can't believe I just wrote that -- never have done it before!)
