Tour on down to Legendary Motor Cars in the Milton area. There is a donation box for entry into Legendary with the hope/expectation that each person entering donates $5 ... money goes to charity. My understanding and experience has been that they give a shop tour on Saturdays. I would phone ahead to verify the shop tour though.
Edit: Oooops, I just reread your post and saw the "Port Perry, Brooklin, maybe Pickering" part ... I'm guessing my suggestion is way more of a drive than you guys are interested in.
