Almost any kit that was part of the Revell "Hot Rod Magazine" set of issues...and yes Mr. 57 Chevy, I'm looking directly at you.
With fiddly ill-hinged, poorly fitting doors and trunk it is possibly the worst thing (personally) that Revell has ever offered. I threw one out as a kid, tried another one 10 years ago in my 20's and while I finished it, I pitched it too eventually cause it was so dang catty-whompus. I have just accepted that there are better fitting, better quality 57 Chevys out there and will never touch that kit again. The entire experience has turned me off to any kit that has "real working doors", or attempting the feat of making my own on a kit that doesn't.
For the record this is a complaint about that kit, I don't think '57 Chevys in general are ugly.
