Serious mods: how common are they?

From time to time someone will suggest to me that TrueDelta’s results might be distorted by the popularity of vehicle modifications–mods–among forum members. After all, many people learn about TrueDelta’s research through my forum posts. In response, I’ve been planning to ask panel members about how much they’ve modified their cars, and adjust the analysis accordingly. The resulting questions were… More →

What does it take?

When the Vehicle Reliability Survey first goes out near the beginning of the month, over 1,000 people responded in the first two hours. Now we’re at the end of the cycle, and I’ve been pushing to get six models that are just a single response short over the hump. Nearly 200 emails were sent this morning to panel members who own… More →

This research is a team effort

I decided to include a “pep talk” in the first follow-up email that went out to members who didn’t respond to the initial email. It went like this: This research is a team effort.

No doubt many people think that cars with problems provide more valuable information than those without any problems. But this just isn’t true. The primary goal… More →

First 2,000 responses in just under 12 hours

The Internet is an amazing instrument for survey research. As long as vehicle reliability research was conducted by snail mail, firms conducted surveys only one a year and took months to release the results. I developed TrueDelta’s reliability research process to take advantage of the much quicker turnaround times enabled by online surveys. And yet I didn’t imagine how rapidly… More →

Cleaning and lubing – should they count as repairs?

I’ve started to review the survey responses for the quarter, in preparation for releasing preliminary results to members in a few weeks. As always, this process leads to tweaks, as I refine the rules of what does and does not count as a repair for the purposes of this analysis. A tweak I’m currently considering: excluding cleaning and lubrication as maintenance… More →
