Autotrader, arguably the best site for buying and selling used cars in Canada, is allowing people to list their cars for free. The listing will only be shown on the Internet and will not be published in their print publications. Take advantage of it now!

The only problem with the free listing is that there are numerous fake ads now. If you are shopping for a car, and a deal seems to be too good, it’s likely a fake and that is collecting email addresses or phone numbers. So be careful out there.

If you’re part of the league of Porsche-nerds like me, you probably know what a 997 is – it’s the latest iteration of the Porsche Carrera models that debuted in 2005 (previously 996, 993, etc.). I’ve been tracking used prices of these cars for the past few years since I’ve considered buying one for some time now.

I’ve noticed a few of my friends have also been looking, so I’ve summarized some of the price trends over the past two years from Autotrader:
