We almost bought new. One thing to consider when needing warranty work, the major shop near me has a list for who gets in for service, starting with their own customers who bought from them. Those who bought used somewhere else go to the bottom of the list. Guess what that's like in the middle of summer. They are the only shop within hundreds of miles that can do all repairs including chassis work and has 40 service bays.
In our case the previous owners did not work out all the bugs. Nothing major but it all adds up. Since we had very little in the way of service records we took the coach in and had the shop go through things and had everything serviced. After all is said and done we will have spent about $5k to have the coach serviced including any chassis work, a front end alignment.
The new one we almost bought. Top of the line with all the bells and whistles, a new 2017 at about $200k off MSRP. Coach was at Freightliner when we looked at it, in for warranty work. Bad sign? Well at least it's getting fixed, we thought. Couldn't get a straight answer about why it was at Freightliner?? A bad sign? The floor plan was perfect and there were no smells of smoking or pets being new. After 2 months at Freightliner the coach is back at the dealer and ready for us to do the PDI. Three mirrors fall off on the short drive from Freightliner to the dealer. Not to worry, dealer says warranty will cover the repairs. HWH levelers don't work, fuel gauge not working, generator bay door won't close, two medallions fall off cabinetry after being touched. This went on for about an hour when we decided we didn't need the problems. Salesman says "no problem, the warranty will cover everything". Turns out the coach is back at Freightliner and the model has been discontinued, therefore getting parts in the future will be a nightmare. The three mirrors were on order to be made, there were no parts left in inventory for repairs when they discontinued the model.
We got our deposit back and bought used with the thought that even if we put $50k in unforeseen repairs on the used coach, we would still be far under the cost of new.
Would I buy new, yes I would, this time it just didn't work out. Yes the warranty would cover all the broken stuff, but the dealer was out of state, about 500 miles away. The shop near me would have put us at the bottom of the waiting list for repairs, even though they are a dealer for the brand we didn't buy.
