Buying Used Cars

I was looking at autotrader.ca the other day, and I found a deal on a Pontiac Sunfire. The Sunfire isn't my first choice in cars because I feel it has a "mass-produced" image (there's too many of them!). However, it is one of the cheapest cars you can buy...lol...so... The car I found was a 1999 Pontiac Sunfire GT, black, with pw,pl,pm. There's alloy rims, a spoiler, and a cd player. It has 150,000 km on it...not bad. And the sale price is $3900 (that's in Canadian dollars).
