My husband is building his second FFR Roadster....

I would like to get him something for the car for Christmas... not a shirt or key ring, but something for the car...

What would you suggest that I could get, that wouldn't be something he would need to choose in order to be sure it was compatible with the rest of his mechanical build? A certain gas cap cover, 5 point harness, or is there some cool "nice to have" that you would not have necessarily bought for your own build but would love to have...

Thank you!
