I realize I'm replying to an old thread, but I wish I heard of Manny before as I used to live nearby.
Since I lived in Stoney Creek, at Fifty Road, so took my Vette into Queenston Chev on Centennial.
First to price out tires. $800 each rear and approx $600 each front @ the dealership.
I ended up shopping online, got all 4 tires (Z Rated) from the USA delivered to my door for approx $850 total including shipping, etc.
I took them into Queenston to get them mounted & balanced - about $25/tire.
BUT, I asked the dealership to return the 2 rear tires as there was plenty of tread wear left on them - was planning to resell them on Kijiji for a couple hundred.
When I got to the dealership a mechanic who drag races finished his shift, took my tires and left. They were not able to recover the tires.
Needless to say I never went back there again.
Few other bad dealer experiences (Mississauga & Grimsby) including from one dealer I see advertising on here.
We spend a lot of money on the Vette's yet some dealers use 'new' mechanics on them.
A couple of times the 'oil life' sensor 's not reset, or they leave oily hand prints all over the fenders.
Now Ive started using Stingray Auto in Mississauga.
Hope this info helps somebody.
