I find the Ottawa Citizen's "Driving" section to be a nice read. It's got an automotive crossword, a troubleshooting advice column, a couple of road tests and vehicle previews. Unlike a lot of newspapers, this section is much more than just a bunch of advertising with one or more articles grabbed from the news wires.
The National Post used to have a nice section, but it's really gone downhill. Even though it shared some articles with the Citizen, being part of the same newspaper group, it had enough original content to be interesting.
I like the regular contributors like David Booth, Graeme Fletcher and Howard Elmer. I haven't heard much from Robert Botselaar lately which is too bad, since he writes very nicely and has a genuine enthusiasm for the craft.
Both newspapers' automotive sections are on Fridays.
