My commute is 45 miles each way. Traffic for my drive can be a bit rough. Therefore I went with the automatic. I don't bother with the tapshift except for on the rare occasion. I got the V6 but even at my reserved driving style I average 23 MPG.
MY reasons for the V6 car are... less initial purchase price, regular fuel, softer suspension for a daily driver, tires cost less to replace, brakes will cost less when I wear them out, and less to insure. Basically I'm cheap but wanted a Camaro Convertible. I did get the 2LT as the heated seats extend the top down driving season. It is my daily driver. However I do have a AWD Traverse for the bad weather.
My main concern would be the parking. The Camaro is a large car and you may not squeeze into the spots you are used to.
