Mr. Leitner - Many of us have the need for a black color as well as those who like metal (chrome or brushed). The H2 offers the Lux and Adven package for H2 - the Adven package is black, so there are plenty of black gas caps out there on our H2s - I know a lock cap would be wonderful given the potential for people to destroy cars by dumping stuff (sugar) down gas tanks of costly rigs like our H2. Will wait for information for your product

Thanks
