First of all, congratulations on your new vehicle! Be careful with it and take care of it! Watch where you park, especially in high school parking lots. You'll literally be the center of attention at school now lol.
Secondly, an automatic transmission does not belong in a sports car such as this one.
Sure you have paddle shifters and such but it still doesn't give you the full experience that this car was engineered and created for. The auto tranny will only dull the pure driving feel that the manual gives. However, if you don't give 2 hoots about driving experience, etc then by all means buy an automatic.
Just my 2 cents. Cheers!
