Going with KJD's comment 1200-1500 on average, I sold one earlier this year for 1900 but I went through it top to bottom.
When looking at a 318, ask yourself, 1) when did the seller buy it? 2) what did the seller do to it/with it, and 3) why is the seller selling it. It's your money don't regret buying something with a shiny paint job, I learned that real quick!!
