Cool New Nascar Diecasts

Some of you may know I've recently been picking up some Nascar stock cars etc...  Well in my latest batch I got a bunch of 'Roaring Racers' from Racing Champions.  These are old, I mean sort of pre-millenium manufacture so I need to let them free from their packaging so I can change the batteries (2 x LR44), here's a short video of two I already replaced the cells on.  One was perfectly clean inside, the other had one cell that had leaked a bit, but its amazing what you can do with a bit of tin foil

Enjoy!
