And Car & Driver agrees with you
"Not A Pretty Cabin
With the exception of the $1995 Recaro seats and the material covering the steering wheel and shifter, the rest of the Camaro interior reminds us of the General Motors that went bankrupt. If it weren’t for the interior, nothing about the 1LE would feel cheap.
And yet, we’d be willing to overlook the interior and the lack of outward visibility to park a Camaro SS 1LE in the garage."
C&D are very high on the Camaro SS 1LE performance, but don't like the interior or the visibility. 2015 Chevrolet Camaro SS 1LE Test – Review – Car and Driver
There is no doubt that FORD could engineer the "track pack Mustang" to be every bit as good as the Camaro SS 1LE. I suspect their marketing data has told them that something else is preferred by the biggest group of their "performance buying" customers. Pobst describes the track pack performance as "floaty" with springs and dampers that are still too soft - and he is an expert at analyzing the performance of a car on the track. I'm sure the FORD engineers knew just what they were getting with the springs and dampers they chose for the special package.
