That diamond car was made for the 40th anniversary of Hot Wheels. The pink Bus is very rare and the body needed to be altered because it didnt fit thru the part of the old track sets with rollers that pushed the cars down the track- it was too narrow.
Ive got a bunch, mostly '07+ because thats when I started collecting. Ive got a few older ones I bought or traded for though.
I still have all my HW’s from when I was a kid on the same shelves I had them on as a kid.
