Sounds tempting at that price and the devil you know is always better than the one you don't...
My only comment in general terms is that diesels have become less desirable in recent years due to the complexity of emission systems add-ons predicated by the Euro legislation ie. Common rail injection, turbo, DPF's, EGR valves, Adblue etc.etc. They all add complication and they all seem to fail early being the primary cause of any diesel breakdown these days. The repair costs can be prohibitive. Your 2012 Sorrento may be early enough to avoid most of this, will be CR, probably has a turbo and EGR maybe but not too much else to cause a problem. Probably worth a punt.
I'm put off looking at anything much less than 10 years old these days due to the proliferation of systems, sensors and software that nobody needs. Look in the car wreckers these days and a large portion of the stock has not been accident damaged or corroded off the road, they are just beyond economic repair due to a failed module or some such...its a conspiracy I'm sure of it!
