Added a page for each make to provide more direct links to the model information pages. Content will be added to all of these pages in the future.
A GMInsideNews post on the 4th (thanks, Arizona Slim!) boosts site visits that day to 506. Seventy-one people join the panel. Both are records.

Friends and family had been pushing for a redesign of the site's look and feel for months. The last straw hit the camel's back when Jalopnik's review described the original design as "super-minimalist (or maybe 1994-era retro-chic)." The site receives a new logo and complete redesign.
At the suggestion of the administrator of fordforums.com, which has an international membership,
expanded panel eligibility beyond North America. The great majority of the cars entered continue to be from the U.S. and Canada,
but eventually reliability information will be available for all major markets.
Carpundit positively reviews the site. Jalopnik reads her review and writes one of his own. Visits briefly soar, topping 300 visits the day of Jalopniik's review and 200 the next. Then it's back to the then normal 70 to 90. It seems that fame is especially fleeting on the Internet.
TrueDelta begins to recruit a panel for its reliability research.

A new FAQ page provides tips for using the price comparison tool.

Not long after individual selection is replaced by selection of powertrains.
After seven months of development, TrueDelta is launched the evening of the 29th with about 65 models in the pricing database. Ten people use it the next day.
