It's not a typo - the ad is on rvtrader.com. Along with some other newer models at a similar price.

This Lazy Daze is beautifully restored/updated and might actually be worth an above average price if the buyer could be assured the chassis mechanicals and underlying systems (plumbing, electric, appliances, etc) are equally good, but that would take a through inspection by both RV and chassis pros to determine. A very risky gamble for a newcomer to RVs.
What questions to ask? Where do I start, since EVERYTHING is at risk? Tire & batteries, of course, but also roof and window leaks, plumbing system, water heater, furnace, air conditioner, etc. It's an entire furnished house that has its own water, electric and sewage utilities, all of which have to work flawlessly to enjoy. And even if it all works well today, it's still 35 years old and has 93k miles on the mechanical parts of the vehicle. Would you expect years of trouble-free use of a 35 year old car with 93,000 miles?
We have RV Buyer "pre-delivery" checklists in the forum library (the Checklist section). Here's one of the simpler ones created by one of our members - read through it to get an idea of what needs to be reviewed if you want to be assured everything is in good shape.

I would say that a fair price for this coach would be in the vicinity of $13k-$15k. That's well above average for a vintage class C motorhome and reflects the extra value of the Lazy Daze brand & quality, but still makes some allowance for its age and mileage. I found a couple late 1990's Lazy Daze coaches that sold in that range within the last year or so.
