Dealertrack is a great system for pulling bureaus and accessing lenders!
I use this program every day and have been very happy with it. It's especially nice that it has the option to export the contents of the worksheet to other systems I use regularly (ie: dealerpull and walkaway). I am very happy with this program.
The direct access it gives to multiple lenders.
Sometimes the deals get stuck between me and another lender and I have to call to get it pushed through.
