wow thats pretty sweet even gives u how many were built with the same options

 

Nice find, I was really hoping for a build date but it's pretty cool to see that my car is actually one of thirty four. Some options on there I need to revive...

 

i looked up my truck it says its 1 of 3 knew it was rare just didnt think that rare

 

thats pretty cool, mine was 1 of 23 with those same exact options, super rare lol

 

my monte is 1 of 1140 not so rare but eh

 

I think they might not have in all the info, because some of those numbers seem really crazy.

 

well i know the monte is about right, & the truck i got is rare its a fully loaded w/t with all power so

 

yeaa, they are kinda high and seem kind of random, but you never know i guess..

 

checked it out and saved it for when i can actually look at it a little closer, thanks
