Construction wise both models are almost identical with virtually all the red painted areas being die-cast metal. The front panel is a separate clear plastic component which has been over painted to produce the body panels & window surrounds. The die-cast baseplate found on the OOC model has been replaced with a plastic one, but this still has a similar level detailing portraying the underbody components..
All the plastic & metal parts fit neatly together with no ungainly gaps and in this aspect there seems to be no difference between this & the more expensive OOC offering.
The new model also has a few improvements over the original OOC, the air vents above the rear entrance are now larger and the front dash panel now has a larger recess for the registration plate, strangely the off-side air grilles haven't been amended and are still based on the mock up vehicle and are thus incorrect justas they were on OOC version.
