These guys are a little tricky to get to (just west of downtown past where the LRT tracks are crossing 10th), but they are worth it! They are very honest, their prices are fair and they won't try to up-sell you on something you don't need. Being female, I spent a lot of time and energy arguing with mechanics as to what they insisted was "necessary" work, when in reality all they wanted was to help themselves to my hard-earned cash. I trust these guys implicitly - if they say it needs to be done, then it needs to be done. I will go to them until a) I move away from Calgary, or b) they shut down, which I don't think they will as they've been around forever.
