Will be watching this for sure. Locally there's a white Murcielago Spyder like the photo, just w/o the logo on the door.
There is just no excuse for undersized resin on very expensive transkits. NONE.
Whether it's built right away or stored, it won't matter...if it is the resin shrinking, and say it was put on the model before it shrank, it won't miraculously not shrink on the model...it will cause big problems.
I'm pretty sure it's the original molds that have shrank over time and with production. I've never seen issues like this in resin from the US, but w/Hobby Design and the resin in some of the Fujimi kits, it seems to be a definite issue.
