Dealership - not yet in my experience, or rather not unless you are made of money.
Peugeot - my 307 drives well and the problems I've had I've sorted out without too much hassle.
That said, nothing major has broken yet and I would like to keep it that way with a decent checkup.
Now I'm looking for someone else with a Peugeot, that services it outside of the dealer network and is happy with the service they get.
Had a 307 for 5 years and only had the battery replaced. Sold it in Feb this year - last services were done by Carlos W Power but they in Pretoria - excellent service.
