JV's Stuck Throttle Cafe'

I honestly didn't think the summer heat could do this much damage to a car interior, but my 2020 Velar has gone from looking showroom fresh to looking like it's been through a war in the space of about six months and I'm genuinely gutted about it. The leather on the driver's seat has started to crack and look really dry despite me trying to condition it regularly, the dashboard has developed this horrible sticky feeling that I can't seem to shift, and the sunroof shade has started to sag slightly which I'm told is a common issue with these cars in hot climates. I know Range Rovers aren't exactly known for being the most reliable things on the road, but I didn't expect the interior to deteriorate this quickly and I'm starting to worry about what it's going to look like in another year or two if I don't do something about it now. I've been looking into getting a proper interior restoration done by people who actually understand how to treat high-end leather and delicate trim, because I've tried various cleaning products and conditioners myself and nothing seems to make much of a lasting difference. A friend who drives a Sport mentioned that he had his car done by a place that really knows their stuff and said they offer premium Range Rover detailing in Abu Dhabi, which sounds exactly like what I need because I want someone who understands the specific materials and finishes that Land Rover use rather than just treating it like any other car. I'm particularly keen on getting the leather properly cleaned and reconditioned, and maybe even having some sort of protective coating applied to the interior to help it withstand the heat and UV damage that seems inevitable in this climate. Has anyone else had their Velar or other Range Rover interior professionally restored, and were you happy with the results? I'm hoping it's not too far gone and that a proper professional treatment can bring it back to something like its former glory, because right now it's genuinely depressing to get into the car every morning and see how much it's deteriorated. Any advice on what sort of treatments actually work versus what's just marketing hype would be really helpful, because I don't want to throw money at something that isn't going to make a real difference. Also interested to hear if anyone's had success with ceramic coatings for leather or fabric protection, because I'm thinking that might be the way to go to stop this happening again in future.
