While I haven't used them for my MINI, a lot of NoVA folks on another auto forum I am on have had GREAT results with lims. Just judging off the work I have seen from them on other vehicles, and a wide array at that, I can only assume that they take each car as a source of pride. We've had guys with old classics, to brand new, off the lot into the shop conversions done, and their work seems to be pretty top notch.
Like I said, I have no personal experience with them, but my folks who have, I trust their input and know that if they say it's golden, than it must be.
