The sides on the AMT 1970-72 Chevelles have always had a wierd side sculpture. Almost like an artist rendering reflection was interpreted incorrectly. The MPC Chevelle had better sides. Unfortunately the MPC 72 annual became a NASCAR racer and it was ruined for stock. As a return as the SSlasher, it had some funky details. You can fix it.
The Revell snap has the best side features, IMHO
