I'm looking to get into a '16 or newer V12 preferably with 7500 miles or less. I know I will get 7 years of free fluids and will try and get at least the powertrain warranty for as long as possible. Do people do leak down testing on the engines or is this silly as they are too new? How long before modern F1 clutches need to be replaced? Do you really need to pay thousands for an independent inspection of a car this new or can the selling dealers be trusted to have reasonably vetted the car?? I appreciate any thoughts.
