Just had the 3rd year service carried-out by Jem Suzuki in Colindale.
I am usually very critical of dealers and dealer servicing in general... so was pleasantly surprised by the service at Jem.
The service advisor was extremely attentive and helpful and carried-out various other bits I asked for at no extra cost.
And, their prices are very reasonable (for dealer service prices, obviously, I imagine a good specialist will still be cheaper).
The only slight downside is that their customer waiting area isn't as posh as some of the other dealerships (and the coffee machine was broken today...
), but on the plus side there's a very good view of the shop floor in case you want to see what is being done to the car.
All in all it was a very good experience and I would recommend Jem to anyone who is looking for dealer service.
