These two die casts have been in their boxes ever since we came back from Germany 5 months ago. I was surprised the boy didn't want to take them out to display, but he said he wanted to keep them clean and not get them dusty. We went out and bought some collectible cases for them today, so he was happy to finally take them out for display.
The detail on both of these are really good. Check out the interiors and the carbon fiber roof on the M3. When comparing to mine, the die cast is really accurate.
