In the 90s I ran a well-known 1:43 diecast website. It started out simply as a way for me to sell and trade models on-line. This was early days of online buying/selling and eBay. The website got popular and eventually I had manufacturers sending me models for review and collectors around the world helping me. The growth quickly got out of control. I was just doing this for fun in my spare time after running my engineering practice and I had to shut it down. Thanks to the Wayback Machine, some of the website is still viewable.
