Looking to buy a Used Defender

I’m currently in the market and looking for a Land Rover Defender. I’ve had other luxury SUVs and still have one currently but I’m looking for a new daily driver and at my local Land Rover dealership they had a few options of new Defender 110s on the lot for around 75k-102k. Having only owned Mercedes and Porsche vehicles. I’m new to Land Rover. When I went to the dealership, they let me test drive and showed me a 2023 Land Rover defender S 110 with 13k miles on it with a retail price of $77,945 but currently has it listed as a past service vehicle for $65,999. I was told that it is a CPO that has a four year warranty 50,000 miles that then turns into a five year unlimited mile warranty from when it was first sold. This also offers an extension of bumper-to-bumper manufacture warranty. Is this a good deal and or should I negotiate off the price a little more? I’m not in a rush to buy a new SUV as I have until the end of the year. Should I jump on this or hold tight?
