I just purchased this kit, and yes the parts are a tight fit in the box. My kit had the bodyshell of the '64 Galaxy twisted and the roof is bent in the middle. No problem I thought I'll just request a replacement part from "round2 models". Yeah right ! After filling out the request form it would not accept the photos even thought they were smaller than the maximum allowable size,therefore they would not accept my part request.
This is very poor service, I even sent an email detailing the issue and of course there was no reply. Overall this has been a disappointing experience for a quite expensive kit.
