It is always hard to value something you have not seen in person. Also you may want to highlight recent maintenance of expensive items like brakes, batteries since this type of documented work has real value. I just paid 18400 for a 2012 35D with 57k, it's a sport that is loaded with packages and options. I paid 160.00 for an inspection and will pay $900.00 for shipping. I think the internet creates more of a buyers market. The post below is from a recent sale. You are right the dealer will not give much. I used to be in the business. You make your money when you buy your inventory for the right price. (low)
