Our jump from 30 Used per month to 130 was no accident. A year ago we priced by gut or by rule. "Add $3000 to our inventory price" is what many dealers continue to subscribe to. We found religion with Dale Pollack and Vauto. Of course there are other tools out there. I like what Dale Pollack has to say and thus went with his product. (no, they didn't pay me to say this). Our experience selling used cars is that we could spend any amount of money in the local "Auto Shopper", local classifieds, Autotrader, Cars.com...anywhere, any amount - and not move the needle. Price a car right in just one venue and customers FIND YOU. Using an etool to monitor the market DAILY is imperative.
Weekly price changes should become policy. While used cars were once one of a kind vehicles, they are now commodities much like corn or beans. If you were investing in commodities on the mercantile exchange you would certainly pay attention to your holdings. This is equally true with your used cars! Seasonal changes, interest rate changes, availability, change in the model year, incentives all play with prices daily.
If you are now flying by the seat of your pants, stop. Get yourself a pricing tool, learn how to use it and make it part of the fabric of your business. Those who don't employ this technology are bound to loose business to those of us who watch our inventory religiously and act accordingly.
