I have a friend who collects classic cars

It is a risky business. He had some are really worth a lot now. And others just bust. 

如果就買一輛的話，就看你的眼光和運氣了。

One time, he drove a really good one out to a car show. On the way back, he was followed. Someone tried to rob him. Luckily he was very alert, and called his buddy before arrive home. His buddy took out heavy guns. Those guys run away when they saw it. lol...
