it cant be correct, i tried all kinds of bikes i have owned over the years like for instance yamaha rd 350lc, only a hand full left, but if you go on to ebay theres more on there than in this data base, how does that work? or for instace i also had an xr4i, my first car - only 2 left, but loads of these were used for kit cars so where are all these? not just the xr4i but the sierra as a donnor for the haines roadster, there must be loads out there.
and then (z3) 1998 zed only 16 left, you must be kiddin, most 1.9z3 are 98s (maybe most z3 are owned on a time share basis) fascinating site, i could spend hours just checking out old cars and bikes i have owned, shame you cant search number plates and see there history after you sold them (in hindsight this might not be so good).
