Fluctuation in the exchange rate probably also has some bearing on prices. I'll have to check the price sticker on the box, but earlier this year I bought the Revell Germany VW panel van at the same local store. I remember paying more for it than the pre-discount "sticker price" of the Lufthansa shuttle version I bought last week.
From what I have seen at the local shop, when both Revell USA and Revell Germany are offering the same kit at the same time, the German one is priced a couple bucks higher than the run-of-the-mill US version. I've heard that some of the racing and exotic car kits are worth stepping up though, because the German version usually has a better decal sheet. I don't know if that applies to the US subject matter like Mustang or Camaros though.
It's even better if you are fortunate to have a local hobby shop that carries the Revell of Germany items. I was able to get the VW Type 1 Lufthansa shuttle locally. I'm not sure what the retail price is over here, but his sticker was $32, right in there with a lot of domestic kits. The owner is a member of the local IPMS chapter. Normally, fellow members get 10% off the top (which covers the sales tax, at least) but this week his e-mail included a 25% off coupon. I don't remember seeing the kit online anywhere under $30, let alone $24. Now, to find the Lufthansa blue and yellow paint. Revell of Germany offers that, but doesn't export it here...
Two-tone wasn't available on a '62. The '61 had the trim around the cove to facilitate two-tone paint jobs, '62 eliminated that trim. I'm pretty sure, too, that the second color in a two-tone was limited to the coves (but not the hard top).
About ten years ago, someone commissioned a "private label" reissue of the AMT '32 Ford coupe in an original style box. The parts inside the box didn't match up to what was shown in the box art, but I'd bet the decals are pretty close to the originals. Do a search on eBay, and look for coupe kits in a box that looks like the original issue.
I've seen one done with an old Revell multiple-piece-body '59. As I recall, the AMT '62 rear half was pretty much cut so as to fit the Revell body minus its original rear section. Between those two kits and a Model Car Garage photoetch set, you should be well on your way with the body. After doing that much work, you'll probably want a better chassis though.
The 'Vette guys are like the Mopar guys in that they've got to find something, anything, that makes their particular car a "one of one", the "first" or last" of something, or something however minor that differentiates their car from the 99 others in the same color with the same options. If it's a regular 'Vette that happened to pass through the Yenko dealership, that'll be enough for some of them, especially if their car is crossing the auction block anytime soon.
But some of the details of the model didn't match what was in the box. The kit never had a filled-in grille area as is shown on the box art model, and the wheels shown on the built model weren't in the box either.
I'm pretty certain the front fenders are the same '60-'66, but the hood was changed for '62. The '62 hood was designed by Tom Daniel during the brief period where he worked for GM. That's probably why he later used the '62-'66 front clip when he created the S'cool Bus for Monogram.
