Hello, I am finally fulfilling my dream of purchasing a 2010 Coleman Evolution E3. I was able to track down 5 for sale within a four hour drive from me. All are listed at $10,000-$11,500. The NADA guide is showing they are worth $6,995 on low end and $8,455 on the high (both of these prices are including the upgraded pricing for the optional AC United added. Could anyone help me with an idea of how much to offer? Are the NADA guides correct? I don’t want to get ripped purchasing something that isn’t worth what I purchase it for and I also don’t want to offend these private sellers with a offer price that is thousands less than their asking price. Please help!
