CAT SX2&SX3 Pro C/F Kit

I recently saw these two kits for sale at a very intresting price. It was the SX3 actually that was offered together with an 'almost complete SX2' for free. I had no idea what versions of cars or what was exactly missing on the additional SX2.But the seller had this auction listed for about the same you'd pay for a Rere Hornet in your LHS. So i took my chance and at the end nobody else bid.
What i got now are two PRO-Version kits, on the 'incomplete' SX2 i found an opened parts bag but all of the parts are there so at the end i'm very happy that i got these two for a real bargain.
I know these are not yet to be called vintage or highly collectible but i'm a big schumacher fan and i just had to grab them while they're hot:-)
Thanks for looking
Mike
