Purchase advice RR Classic V8 Automatic

Hi, I’m currently looking for a new off-road car. I’m currently driving a Jeep Wrangler in my everyday life, but I’d like to switch to a Land Rover again. About 10 years ago I had a Defender 110 TD4, and now I’m interested in a Range Rover Classic (RRC). After some reading I got stuck with a model with the 3.9L engine and the 4-speed automatic. I’d like to hear your opinion about this car: [Link to the vehicle on mobile.d e](https://suche.mobile.de/vehicles/details.html?id=407777383) If I understand this correctly, the camshaft and the control chain are considered weak points in this engine, right? Do you know what the parts cost for a repair and if you can do it yourself, if you are somewhat skilled in craftsmanship? Best regards Ele — Let me know if you still want to make changes!
