My leased 10 month old £64k Velar is currently in the dealers having the engine removed to replace the balance shaft bearings, after just 7k miles. The courtesy car they have loaned me (also a 1 year old Velar) has the paint peeling off the bumper.
The quality of dealers does vary, but generally you will find more empathy and better customer service at any other main dealer.
When they work, they are lovely places to be. VERY comfy, superb to eat up the miles - particularly if you have an air suspension model. The issues come when they dont work (which WILL happen), you will question why they are so badly built, why they cost so much and why the customer service is awful for a luxury/expensive brand.
Make sure it has a warranty for the entire period you own it.
Expect every bill to be 3 figures.
Despite all this, they are such lovely cars that I keep coming back to the brand, even though I have moved away from them several times now in utter exasperation at how badly I have been treated and how unreliable 90%* their cars are.
(* this is a totally made up statistic...)
