ooooh, Chrome! <<< use Homer Simpson's "uhh, donut" voice>
Personally love the idea and would commit to quite a few - however the chrome might be a little too close to the factory metallic silver - how about a gold chrome - yummie!! It would be especially cool if the packaging had some type of sticker "VehiCROSS Owners Club" or some such (like the hologram sticker on the Factory Sealed sets). If you need some more examples of diecast toys, you can reference my page:
