It's interesting that it was mentioned that 50 years ago the main market for model cars was kids and today it's old cranky guys. Well guess what - it's the same bunch of people! It's us Baby Boomers. It's me! Back then we didn't have much money, and didn't care about fine details. We just wanted to build them quick and easy. Now we're retired and many of us don't have a big income, so those nostalgic old kits are once again appealing to us, so we buy them. What's better now is that we do have many new generation kits made from new, improved tooling with great detail, so we have a choice. Eventually we, and those old tool kits will be gone, and all the future kits will be the best that modern technology allows. Also injection molding technology has made great strides in 50 years. The detail we see in new kits simply was not possible in the 1960's.
