These are a pretty close match for the Impala grey interior. They are the Summit simulated leather racing buckets, I got them from Drew. I installed them in the car and they look AWESOME, but I think I have changed my mind and am going to install my 02 WRX seats that I absolutely LOVE. I know I will have to recover them, but it won't keep me from driving the car, so I think that is the route I am going to take.
Pic installed in the car: (They look dirty in the pic, but they are not, they are like new)

I bought them from Drew for the same price as new because they are mint and he included an adapter he had made to match to the Impala rails. I am keeping that adapter setup he made to adapt my WRX seats. $200 for the pair of seats, no adapters, and they are yours! (The adapter is really just a piece of flat stock with the correct holes drilled)
