Where to look for used buggies
 

My neighbor has taken a liking to my son's Carbide 150 and now he wants one. Problem is we've both looked around the internet and can't seem to find any used ones for sale anywhere except for one in Grand Rapids for $1900. I'd like to help the guy out but I just don't know where to look anymore. 5 years ago you could use search tempest and find all sorts of stuff on craigslist. Seems nobody is using CL anymore.

Also, I should add, we are in South Central Indiana
