Does he have a fine car? If so, you can buy him some accessory for it. Go into the service department of a local dealer for that car. There will be some stuff there. You can also find stuff online.
If he doesn't have a fine car, but you know what he'd really like to have, you can get something that has to do with that. For instance you could get him the BMW leather jacket or the mercedes baseball cap.
Going in a totally different direction, you could make him a special dinner. Or pick something else you like to do together.
The very best gift shows that you really like the person and the you know them well enough to choose something they would like.
My wife's favorite gifts are the ones I give all year long. I do some obnoxious chore that she hates. It keeps that looooove powerful
