I have done that before. I bought a 1984Centurion Elite RS for$100 and rode it for 2 years. I actually liked the bike a lot , it was just not the seventies or Euro bike I usually roll with. I listed it on CL for $300(it was like new and all original) and sold it within a couple of days .I put the money in my sock drawer and , wouldn't you know it, a 1977 Raleigh Competition GS showed up on CL for $300 that was in just as good of shape as the Centurion! It wasn't planned , but it just worked out. My wife just resigned herself to my obsession .
