Lemme just put it this way.... while i've had better service with Devon than i did with the plethora of other dealerships i had to go to when i had my 2009 Brabus Coupe (after the ORIGINAL Devon closed down), I'd still rather change the oil myself. Not only because of the $120 cost of the oil change, and the seemingly incredibly long wait JUST for an oil change.... but the fact that, for me, I'm also using over half a tank of gas just to get there and back.... so another $15-ish on top of that.
Nothing beat the original Smart Center Devon, though. When i picked up my 09, took it all the way home.... realized that there was a gouge in the lip of one of the wheels on the car... more than likely from when it was taken off the car carrier. Took the drive all the way BACK to them the next day... they swapped the wheels on mine with one that was on the showroom floor so i wouldn't have to wait for replacements. They also took my car to get it washed. Any time i took the car there... whether i was getting it serviced, or if i was just in the area and popped in to say hello, they'd wash my car for me if i wanted them to. When my car started to experience a water leak at the top of the rear glass panel between the glass and the window frame, they ordered one... but when it took too long for it to come in, they just swapped the whole assembly with one from another car.
Then... they closed (which the former Smart Center Devon was what is now Maserati of Devon, right across the street). Went to Cherry Hill once... for an oil change and check up. There wasn't a soul around the "smart center" part of the dealership. Got the bill, said there was a "complimentary wash and vacuum".... which it was blatantly obvious to a friend of mine who went on the drive with me, and myself, that neither was done. Went to one in northern Jersey... can't remember which... but don't remember if i was all that impressed or not. Then we finally got one back in southeastern PA.... Smart Center Trevose. UGH!!! Worst.... Dealership... EVER! That freakin hell hole has forever basically made me gag whenever i hear mention of the Faulkner dealerships (cause it was part of the Faulkner dealership in Trevose). Went in there one time after my wheels had been pretty badly dented from our lovely PA roads.... and since i had purchased a wheel and tire warranty when i bought my Brabus (because those wheels were EXPENSIVE!), I asked if they could help me get them checked out and repaired or replaced. The guy behind the counter LITERALLY said to me "well... we'd have to have someone look at the wheels". A)... no sh*t, sherlock, and B) that's... kind of what i asked about. That's all he said. Never said anything else about it. Never sent someone to look at them... never asked "Do you want us to check them out?" Nothing. Just kept his ass firmly planted in his desk chair.
Think it says something that with all the hell i've gone through with the dealerships for these cars.... i STILL love driving them and owning them.
