Milners pride themselves on service, this is what makes them successful, combined with the fact that they actually work on, and build their own vehicles. I live not too far away, so it is easier to call in as i pass them frequently, so the problem of incorrect parts does not arise. Many others i have recommended to them have echoed your views, when it is wrong they try to put it right, if not they will give technical advice to those of a more technical disposition.
