September 2008

Posted first results from the Vehicle Reliability Survey.

Upgraded Fuel Economy Survey and Vehicle Repair History Survey to display previously entered vehicles and data.

Added RSS feed.

Continued to upgrade the fuel economy survey. Added databases to support the 2003 model year.

A bad experience with my wife's PT Cruiser inspired an editorial on the logic of out-of-warranty assistance. It's time for manufacturers to realize that standing behind their products even after the warranty expires often makes good business sense.

Patent application filed covering innovative aspects of the pricing tool.

Members can now set their own feature values to reflect the amount they'd actually pay for a feature.

Basic specifications now provided on model information pages.

Cars and especially compact cars have enjoyed a surge in popularity. Since the site began, the most popular price comparison, by a wide margin, has been Honda Odyssey vs. Toyota Sienna. But in recent months Honda Accord vs. Toyota Camry has been gaining ground, and now has pulled ahead. Honda Civic vs. Mazda3 is a close third.

August 2006

Monthly update pushes the daily total over 1,500 for the first time on the 29th.

Thanks to a TTAC editorial on why just knowing the top scorers in a reliability study isn't helpful, posted on the 28th, it's also the first time daily visits exceed 1,000 for two days in a row.

MazdaForums wants to host a banner to help out, so Robert Staddon creates a couple for the site. They can be viewed at the bottom of the About Us page.

The list of most popular price comparisons is now based on the last 90 days. It will be updated at least once a month.

July 2006

June 2006

Vehicle Comparison Survey launched on the 26th.

Low interest rate deals can now be calcalated with the appropriate adjustments to rebates. Low rates, if available, will be shown in the "recalculate as payments" section of the price comparison results page.

Combined with the ability to report employee prices, it will be possible to learn which deal is best during this summer's big sales.

On the 13th, an enhanced version of my critique of J.D. Power's 2006 IQS is posted to The Truth About Cars. Daily site visits top 1,000--the first time this has happened without an assist from the monthly update. The panel grows by 52 vehicles.

A list of models currently being surveyed has been added here.

January 2006

On the 14th, the 100th Honda Odyssey is added to the panel. It is the first model to reach this milestone. The Honda Accord and VW Passat are not far behind.

December 2005

Focus on improving email procedures. Too much getting caught in spam filters.

TrueDelta displays GM's "Red Tag" and Ford's "Keep It Simple" prices. Nothing is really special about these programs, and visitors to TrueDelta display little interest in them.

November 2005

Data collection began on the 3rd. The first round includes 276 vehicles.

October 2005

Everyone hated the bright green type. Well, at least my wife and one other person did. So the type in the headings and logo was changed to a more soothing light blue. If nothing else I feel more relaxed when working on the site now.

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.

Steve Hofer in an entry to his blog labels me "The Hardest Working Car Reviewer on the Web." TrueDelta doesn't receive much traffic as a result, but still very much appreciate that someone recognizes the amount of time I put in.

Added an option package analysis run when a single vehicle is priced. This analysis lists the contents of each selected option packages and then calculates the percentage that was requested.

Daily visits regularly top 200. Traffic has tripled since April.

September 2005

Filed a provisional patent application covering the innovative aspects of the site.

John Neff at Autoblog posts an article about TrueDelta's reliability research on the 6th, boosting visits for the day to 425. The panel grows by 60 vehicles. Both are daily records.

August 2005

Revised the model info pages to include links to the most popular comparisons including the model. Relocated the link to the model name on the complex feature selection page.

Revised the sample reports to more closely resemble those planned. Clarity, ease of use, and practical value are the top priorities.

Revised the survey to make it simpler and clearer.

Updated the pricing tool to save the selected features when the user returns to the feature selection pages. This makes minor modifications much easier.

Many new pages added: a proper home page (finally), a links page, a form making it easy for people to recommend the site, and this news page.

July 2005

Added sample reports. Composed largely of tables, they could be more user-friendly.

Daily visits unaided by positive mention in a blog top 200 for the first time.

June 2005

TrueDelta states that only active participants in its reliability research will have free access to detailed reliability information on the site. The panel begins to grow at ten times its former pace.

Added first draft of the survey to be used in the reliability research.

GM offers employee pricing to everyone, so TrueDelta provides employee pricing on GM models. Car sales surge, and visits to TrueDelta surge with them.

May 2005

A list of the forty most popular comparions is added and proves very popular.

Daily visits begin to regularly top 100.

April 2005

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.

March 2005

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.

February 2005

TrueDelta begins to recruit a panel for its reliability research.

Janaury 2005

TrueDelta gets its first logo. No one likes it much.

Individual models can now be priced without entering the same information in both slots.

December 2004

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

Daily visits top 100 for the first time on the 27th.

October 2004

Early on engines, transmissions, and drivetrains were selected individually. To make it easier to select valid combinations, information pages become accessible through a link on the complex features page. Few people take advantage of it. Not long after individual selection is replaced by selection of powertrains.

September 2004

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.
