Well I can't speak with any knowledge about the event mentioned in the above links nor have I met Zif however Peter has always been friendly and professional in dealing with my numerous questions recently and in the past over several years of lurking around a bimmer purchase. What I have observed of his dealings with other customers has been similarly positive. I have no doubt that things may have gotten hot around the event above but it seems perhaps they were middlemen in that deal so to hold them responsible for the seller's misrepresentation is unfair.
And you loose nothing by calling and talking to them and getting a quote on a job, even if you don't choose to go with them it gives you an idea when talking to other shops if they are offering you a fair price for the job.
Another shop you might try is Europa Motors on Woodbine in Markham 905-415-2269. I've spoken with them before discussing possible purchases and they seem to be good knowledgeable people and also reasonable to deal with.
btw bigd why'd you go and get a mahgwa drunk?
