It looks pretty good to me. You did a good job designing it. For a new site you have a lot of cars for sale.
There are some guys on this site that really know their stuff and have posted some very informative information. Bob Parmenter , Techinspector1, Spray Tech and occasionally Streets to name a few. But like Streets says This is a free site and your's is a commercial venture. If you want to reprint their articles you may have to offer to pay them. I don't think free advertising will do it because they have that here and they don't use it much.
