Information you'll want: help make it happen

Whenever you buy a car, you'll wonder:
- How reliable will it be?
- How much fuel will it really use?
- Why should I pick one model over another?
To answer these questions, over 49,000 people with over 60,000 cars have already joined the TrueDelta community.
When everyone shares their experiences with their cars, we all gain:
- The Internet's most up-to-date car reliability information -- so you know how reliable a car has been lately -- and not just dots
- Real-world gas mileage figures tailored to how we drive
- The reasons people choose one car rather than another

Participating is quick, easy, and free
- Email: To avoid the hassle of signing in, the main survey can be instantly accessed via links in a monthly email
- Odometer Readings: Four times a year report an approximate reading--even if there were no repairs--so we know you're still in
- Repair Report: If your car goes into the shop for a repair, report it the next month using a brief survey form
- Optional: other surveys, including one for real-world gas mileage
For the typical car, these short surveys take just a few minutes a year.
What will I gain?
- Free access to all of the community's car reliability and fuel economy information (guests receive only partial access)
- Those who don't participate will pay for this access; you won't
- Personalized new car price comparisons
- Help other car owners, help yourself. This isn't your typical survey: it's conducted to help participants. More participants = more information for all of us, whenever we need it.
When is the best time to join?
For the highest quality results, the main survey collects data going forward. You cannot join a year from now and report what happened in between.
In other words, today is the best time to join...
