How about getting him a highly-detailed model car kit that he can assemble and paint himself? That way he can enjoy the process of building it and then display it proudly on a shelf or in a glass case. You could also consider getting him a subscription to a model car magazine or a gift certificate to his favorite hobby shop. For an extra personal touch, you could add a handwritten card expressing your love and telling him how much you appreciate his passions.
Or you can get him a star map with the date when he was born.
