Ah! I couldn't get past the interior as well and pointed out to the salesman that pretty all GM cars have the same dull boring interior.
Going through the gears in that car in street driving would seem boring to me in that car. If you floor it in first you are probably doing 40+ already. That doesn't leave much to do after that unless you want to do 160 all the time
In summary it is a car that's way too powerful for street driving.
