Hi, there is this guy wants to sell a wheelchair van for $3100. It is a 1998 Dodge ram, with a V6 engine. As you can imagine it has over 200,000 miles on it. Kelly blue book is pricing the van itself around $1300. My question is, the value of the van conversion and lift in the van worth $1,800? He said that the lift was just serviced for $300.00 and also did minor things like tuneup. It looks like clean van, body is in great condition inside looks clean, the lift is in the back of the van.One more thing he mentioned, is his mechanic couldn't get two of the 6 spark plugs out. He said he thinks that why the engine light is on. What do you think?
