I was purchasing an Used Mazda 3 from a UCDA Dealer that had bought the Mazda 3 at an auction. Even though the Dealer was selling the car certified with Safety & E-Tested, plus 2yrs warranty, I wanted to have a fresh pair, preferably a pair of Mazda-certified eyes check the car. So I called them, told them about my situation, and they recommended the $105 plus taxes 50-point inspection, and made an appointment for me.
I was running a bit late (about 15 mins. behind schdeule) stuck in traffic in the midst of a snow-squall, and a guy from Yorkdale Dufferin Mazda called me asking if I was coming in or needed to re-schedule. I told him I'm running late, and he re-scheduled an appointment 30 mins. after my original appointment, giving me ample time to drive over safely in the conditions.
This was the best $120 (approximately after taxes) I spent. The car had a few extra niggles than the ones I already knew from the dealer. Also got some pretty good off-the-record man-to-man advice being a first time a Mazda/Mazda 3 owner.
