Pretty much everything in my collection was picked up used (mostly rollers), then rebuilt or upgraded.  I have a nasty habit of getting a car 80% finished and then getting distracted by another project.  This has lead to a fairly  large collection of vehicles that don't quite run yet.  Like most of my other hobbies, I seem to go for quantity over quality when it comes to RC cars.
