Having owned an L494 and a 2014 Range Rover with the same 5.0 Supercharged engine as the OP’s, I’m definitely in the positive camp for this purchase.
My first point would be to take comprehensive photographs of the vehicle including pictures of the sawn through steering wheel to illustrate that this vehicle is a Cat N purely due to being stolen recovered and not due to any major body damage. This would help any subsequent sale.
Given what I’ve read here about the previous owner, I presume he hasn’t skimped on maintenance. At this age, I’d stay clear of main dealers and find yourself a decent specialist. If you’re handy with the the spanners and fancy servicing yourself, there are lots of online specialists who sell both genuine and aftermarket service parts. I used to use LRparts.net
Other things that might need attention during your ownership could be the airbags on each corner which may leak. If they do, you’ll notice a drop in height for that corner. These are reasonable cheap to replace. If you leave it too long, it will cause the compressor to work extra hard which may also fail. Again, these are easy to rebuild or replace.
The 5.0 supercharged engine is the best and smoothest out of the lot. The 3.0 diesel is prone to crankshaft failure and the 4.4 diesel eventually require replacement turbos at higher mileage. I never had any problems with mine. The ZF 8 speed gearbox is also very smooth. Land Rover will tell you the boxes are sealed for life. When the car approaches around 100k miles, I’d recommend a gearbox oil change which would cost around £350-£400.
Make sure the battery which is under the boot floor is in good order as a battery which is on its last legs can throw lots of error codes.
If you’re into modding your cars, I’d recommend changing the rear light clusters to the post 2018 ones which will give the car a cleaner and more modern look. Google Powerful UK who sell lots of interesting bits for Range Rovers. They also have a YouTube channel which gives lots of info about modding and maintenance.
Finally, a very good website for you would be
www.fullfatrr.com Lots of owners on there with lots of advice.
Enjoy the car! Given the price you’ve paid, even after a years ownership, I don’t you’ll lose money. There will always be a wide boy somewhere who will bite your hand off for an Overfinch L494!
