My 2016 Range Rover TD6 with 33k miles is approaching the end of a 3 yr lease, with a residual buy out cost about $5,000 below market. I am considering having the dealer CPO it and then buy it, which would allow me to drive it another 3 years under warranty. The catch? During my ownership it developed an oil leak that required an engine-out gasket replacement. It's fine now. Would that discourage you from buying it, even at that savings? Interested in opinions.
