It helps if one can do their maintenance as I do. A dealer oil change and fuel injector cleaning, a bottle of chitt I buy off net, runs $450. A twenty minute job. Plugs, air and cabin filter is $1000. A two hour job... I do my own as, in most regards, is no different than doing the same on my 73 Mach 1.
Ed, have fun with the air filters on a Panamera then
.
Front bumper skin has to come off to replace them.
