I had a 12' 2SS 45th and liked it but going to a 13' 2SS 1LE showed there is quite a difference. Handling is much better, acceleration is better due to the 3.91 gears & close ratio trans, the shorter throw shifter lifted from the ZL1 is better and I like the distinct cosmetic differences that set it apart (wheels, hood wrap, steering wheel & shift knob) .
My only "gripe" if you can call it that is maybe finding the right tire for the 1LE if I need to have it for off season driving. Right now it's a garage queen during poor weather and planned that way for winter months but who knows what the future really holds.
