I have an 89 BMW 735il with gray interior. two questions, which headliner color will match existing headliner and is the BMW package size fit the IL sereis which is a couple inches longer.

The 2165 gray color would be the best color match we have for the light gray/silver headliner in the BMW's. The headliner kit to get is the BMW/Jag/Volvo headliner kit would work, but for the 7 series BMW's. You can add for the sunroof if you need to recover the sunroof portion of your BMW car.
