If it is an Intrigue that is one of the very top coaches made that year if my memory is correct. I believer the RVCG gave it a five star rating in the 42 length. 20,000 miles is low for an 8 year old coach. Lack of use can cause issues with rubber seals and such getting dry. Also motors not run for a long time is not a good thing. You should check every thing before agreeing on a price. These are big complex motor homes with lots of high end fru fru. We really like ours, but we have made good use of the extended warranty we got with it. Stuff does go out. But the bones of this model are as good as it gets.
