Well it doesn't appear the kid fully lied. Every lie has some trust to it. He may or may not have overstated what he sold the domain for. But as I stated earlier anything is possible and the name itself to the right buyer can do very well with it. If I had a car chrome protecting agent I would want to call it ChromeGuard as well. If you start to see infommercials about this you know it's been sold.
Protecting your car chrome is worth big bucks. I am sure there are companies making millions on similar products every year. Why is it so unfathomable that he got $xxx,xxx for chromeguard.com just because he had it for $60 earlier.
Anyways..truth or lies this is a nice thread to read...drama is fun sometimes.
