Do you know of any BMW/European mechanics that are open on Saturdays in the Oakville/Burlington ON area?

Or, if you are in the Toronto area and are good with working on cars, I’d like to borrow you for an afternoon lol (Lunch, gas, etc are on me).

I’m trying to check out a 2000 BMW M5 before I buy it. I ran a Carproof and Lien check on this car and everything looks good.

But unfortunately, I am not mechanically inclined and have no clue on how to check stuff before buying a car.

Since this is the most expensive car I’ve ever bought, I want to be as sure of my decision as possible. I’ll appreciate any help I can get.
