Sometimes no matter how hard you try and avoid giving a negative review about a merchant or service provider you can’t. This is one of those times that so many bad things have happened, you know now you will never use them again because what you might have thought was a fluke, now appears to a pattern. Car-2007 BMW 550I Very nice folks, but sorry that is not enough. Standing behind your work, not making simple mistakes, following specific instructions, and yes, even standing behind those you recommend is part of it as well. Item 1. Replaced Alternator but they accidently disconnected the radiator thermostat and as a result engine overheated, thankfully, I stopped and did not continue driving. They admitted to they missed it. Permanent damage unknown. Item 2. More recently, brought in for noise in front –end. Diagnosed as lower front control arms, upon further research, was told to have them check both upper and lower front, which I did, they said ok. So they replace one of them L&R. As soon as I got back, no change. What was it? The ones they said they checked but obviously did not. Item 3 and maybe not their fault but considering they send a lot of business to this body man Eddie’s (who will be reviewed separately) they had the power to force him to do correctly. Replaced and painted rear bumper which while at Ultimate’s shop (where he picked it up) was clearly pointed out he needed to replace with a new, used, or even aftermarket bumper that also has the back-up sensors. What did he do? He replaced with one without them and drilled the holes (WAY TO BIG) and fudged it. Yes Ultimate said he did a lousy job but obviously not enough to make him do it right. He took it back and fixed the gaps (I guess with Bondo or whatever). Yes it looks better but it’s not right and I know it. So after all this, after picking up the car today. Item 4, I notice my music is not playing, why, because the IPOD connected via the BMW factory IPOD cable is gone, poof! Of course, no one knows why. It’s really unfortunate because there is a lack of quality BMW mechanics (outside of the dealerships) in the Lake Worth/Wellington area. I am disappointed I can’t trust them to do anymore work on my car, it’s a tremendous inconvenience given they are right down the street from me.
