As has been said, you need a good warranty insurance, make sure what it covers and for how long, some only cover certain items and not wear and tear.
be aware that if the engine seizes, the cost of a refurbished one can be in the ballpark of £5,000.
I was talking to my Skoda dealer on Saturday, and was saying that my superb woukd be a good car for them to acquire, but they said Motability want £2,000 above Parker’s for their cars, so they dint buy them anymore.
Strange that Motability send them to auction houses at a No min price….
