I know, the amount is not exact, as deleted cars are not replaced in numbering, but anyway it is nice number to see

One question - I remember some time ago I was searching just for fun the cars numbered 1000, 8888, 88888, 10000 etc - to see in which movie they were, but I am kinda unable to do it with 100000.. Was somehow changed the adressing to the sites, as before it was enough to change the number and the car was found, now also the name of the acr is part of the adress..

The name written in the address is not important. It is there only for Google and as an indication of link contents.
e.g.
http://www.imcdb.org/vehicle_100075-Chrysler-300-C.html
http://www.imcdb.org/vehicle_100075-a-big-american.car.html
both works the same
I do not know why it did not work with 100000 for you
http://www.imcdb.org/vehicle_100000-here-is-the-one-you-search.html
The text after the number can be deleted, but the "-" after the number has to be kept (I should fix that)
e.g.
http://www.imcdb.org/vehicle_100000-.html

ahhhh, there was the problem (in "-") thanks
