Whether you are attracting buyers or sellers probably makes a difference in your ad targeting, of course if you are a regional advertiser you would want to use ad systems with geo targeting so you don't waste your advertising dollars. Expensive keyword targeted 'sponsored search' ads like Google's Adwords might get some of the highest conversions, with some additional research labor, you might be able to place text or banner ads on carefully selected sites or individual pages that car buyers frequent for less cost. The Google ad network, also accessed through Adwords is large. Your monthly budget pretty much limits you to the self-serv category of ads.

Here's a $75 first time Adwords user voucher Google was heavily promoting a while back, this page might still work:

Perhaps if you found the perfectly matched site you could place a banner ad on a specific site found on BuySellAds.com, Facebook has their paid ads as well, which have very good demographic targeting, if you wanted to write an ad specifically for single, college aged males you could find them with Facebook ads.

You can reach a subset of users (who have allowed the installation of legal adware in order to have a toolbar or game platform installed on their system) through CPV (PPV) networks that are able to insert a popup window on any site or page you specify, you can target car magazine sites, other classified sites, cars.com, etc. with timely messages, these sneaky ads are relatively cheap as well.

Although more typically for the hard core marketer, if you had a competitor really bugging you, this is a way to intercept a portion of their visitors. Here are some of these networks

TrafficVance $1000 minimum deposit (the best, referral required)
Lead Impact $200 minimum deposit (often recommended)
MediaTraffic $100 minimum deposit
DirectCPV $100 minimum deposit
Adoori $100 minimum deposit
Adon Network "Pop unders"
Jema Media

Even full time advertisers have to test out different ad designs and traffic sources to discover what pays off, tracking is more tricky for you than a conventional ecommerce site sales page, but you should employ all the tracking you can to monitor what ads your traffic is coming from.
