First off, I just wanted to say that 93,000km is not high. It's literally 30,000KM past its factory warranty. I'd be willing to bet that the in service date was in 2018 therefor been on the road for close to/over 3 years. Hell, it still has the 5yr/100k power terrain warranty left. That covers a lot of the big stuff.
You didn't list a price so I can't tell you if it's a good deal but with a little extra extended warranty added at purchase, I wouldnt worry at all.
And just so you know , every service as small as oil changes are necessarily documented on car fax, etc. I get mine done every 5,000k at my local ram dealership and it's not on the actual car fax report, it's in their own service records.
Just my two cents.
