Good job!  I'll have to agree with Mike that the listings look a bit bunched up making the price of the car above sometimes look like it belongs to the car below and I'm see a lot of framed "white space" on the right side (i.e., an area you expect to be seen - not due to the fact that I'm viewing the website on a larger monitor).  Maybe the price can go on the right side and "Details" could move over a little?  Here's what I see on my monitor.  The blue areas are obviously stretching for my higher resolution, but the white area to the right of "Details" should be available for use.  Notice how the "Cash Price" sits a little below the bottom of the picture.  This is what makes it difficult to tell which vehicle it belongs to.  Just my $0.02!  (And I probably should get change.  )
 

 
I also like how the "About Us" page shows pictures of all your backyard improvements too.
 
(Q:  What did people do before Carfax?  A:  Saved $40)

I've got my website guy working to put a border between each vehicle. Thanks for the suggestions guys.

My first thought was - really ??  Has America really not learned about giving credit to the wrong people ??
 
That aside, As others have mentioned the spacing could be better and as cars 3&4 look much the same, as do 5&6, might be an idea to split them apart or at least vary the pics a little. Change of background, different angle something like that. Not easy to make it look like you have a varied selection with so few cars, but having very similar ones right next to each other  isn't helping IMHO.

The site looks great!
 
Only thing I might consider experimenting with is to make the text a bit larger. This is mainly targeted for the Home page, and I am referring to the detail text under each section. Could also apply to the car detail text in the inventory page. The text looks great, but I found myself straining just a bit (or moving in closer) to read it. Just something to consider for those us not quite with younger eyes anymore.

I agree on the carfax stuff. My daughter's car was in an accident and there was a fair amount of body damage. Nothing structural, but the repairs to the front, side and rear panels was in excess of $5k. Almost to the total percentage. The car was repaired to like new condition by a reputable shop.
 
Someone seeing that on a carfax would likely walk on past the car when there is nothing wrong with it.
 
And totally agree on maintenance. People who do it themselves or with good quality shops that are not on line and reporting service.... as a shop that I use does not..... the car would show up as not serviced according to mfg's recommendations......
 
Site looks good Randy. Best wishes to you.

I know nothing about carfax, but if was loooking at any car that had been accident damaged to a degree that the repair costs equalled the value of the car , I would want to walk away from it.

As for incomplete info, if you get into a minor accident with your car, and take it to a local shop to have it repaired, there is no way for carfax to know unless the shop reports it. On the other hand, if they do report it and it was a minor fender scrape with a minimal cost to repair, and no structural damage to the vehicle, carfax doesn't give any other info other than it was in an accident. It could be a quality repair, and the vehicle could be fine, with many years of reliable service ahead, but the carfax would lead a viewer to thing otherwise.

This happened to us last year when we went to trade-in my wife's car at a dealer for purchase of a brand new car. Prior, she had side-swiped the driver side mirror while going through a Walgreens drive-thru with some advertisement sign they had displayed. This happened on the trade-in vehicle and the only damage to the car was the mirror. Being the car was only a year old at the time, she decided to have it fixed and took it to the dealer for the repair service.
 
Last year in the process of negotiation for a new car with the trade-in, the dealer came back indicating the trade-in vehicle was involved in an accident and used it as a negotiation advantage on the trade-in value. We were initially taken aback wondering when she was involved in an accident. All we could recall was the damaged mirror. We asked if the report indicated what the accident involved, but there was no information. Only that a repair to the car was done. We couldn't believe this type of repair 'qualified' as being a reportable accident incident. Ultimately it cost us cash value in the trade-in negotiations.  

After Hurricane Katrina, a lot of the swamped cars from New Orleans showed up on dishonest lots down here.  These flood damaged cars all had clean carfaxes, it was a big news story.   Some dealer, very near to where I lived at the time, was brought up on fraud charges.
 
Carfax is not accurate.
