BMW after sales is generally very good,it has to be because the initial product is sadly often lacking.
I'm not one of these folks that you see all to often in BMW dealerships,it's all to pally pally for me.
At the end of the day I've given them my hard earned and I expect a level of service.The salesman or the service manager are not my mates they're there to provide me with a service.
Under the surface every BMW dealer I've dealt with thinks their doing you a favour,but at the end of the day, lets be fair, BMW have been left behind in the quality and development stakes but they still want a premium price for their product, so they have to add 15% to the purchase price to deal with the cost of the many many warranty claims.
As for the dealers I feel they have an inherent arrogance that they do not expect to be challenged and are generally full of the proverbial.
I spoke to one of the senior engineers at the Birmingham show this year. Allit did for me was to confirm that I would be very unlikely to buy BMW again.
