I have done numerous of these. They are easy. I take about 5 minutes or less to look around the site. I send in the inquiry, wait for the replay, then submit the report. Total is easily less then 20 mins.
Very easy! You will most likely receive a few emails from them which is a pain, so I don't use my regular email account. Also, it goes without saying, but make sure you follow the times. I always have the urge to do them first thing in the AM, but the ones I do can't be done until 10AM.
That's what I do. I monitor the inbox for the 24 hours after submitting my inquiry to see if the dealership emails me, but I only use it for this purpose. My main email is only given to MSCs, my banks, friends, family, and the like.
Back then...I was really looking for a car, so I was doing email inquires to many dealerships using regular email address...I still am getting emails from these places...which I have to put them to "SPAM" box. I wish I knew that earlier!! O well.
