If you want to get REALLLLY nitpicky... there were two versions of teh Silverstreak. The right-hand drive and the left-hand drive. But even so... Hasbro does not cater to "completists." They put out what they think will sell, while trying to make as much money off of each mold [or base mold] as they can. Some are unfortunately going to be shelfwamers. They are NOT going to take into account how many times Takara has released [essentially] the same figure. They will only worry about their market.
