We've done a full refresh of our data and even added a few new sources. We now have a total of 209 models with depreciation curves, including 3 new ones!
As for luxury vehicles, Lexus remains at the top of the pack. Tesla surprised, and rose a few spots, thanks to the Model S, which has shown strong residual value retention so far. The Model S has bucked the trend of other hybrid and electric cars, as these alternative fuel vehicles typically are some of the most rapidly depreciating vehicles on the road.
Our overall rankings are based on retained value at the 5-year mark. Click here for a complete list of the rankings.
Thanks to user contact form suggestions, we've added 3 new models during this update:
We bolstered our already expansive pricing and sales data by leveraging new technology to aggregate millions of listings from across the country. Using this new technology, data is collected and analyzed from over 40,000 car dealers. Their API is by far the fastest and most robust that we have worked with so far.
We also added more sources to our expected maintenance costs including some data from a new data source. They record and analyze data as reported through their hand held vehicle diagnostics tools. They also release an annual Vehicle Health Index Study, which is fascinating to those interested in these metrics.
Another great resource for repair and maintenance costs is YourMechanic.com. They provide you with year, make and model level repair estimates backed by local repair shops that participate in their program.
Finally, thank you to all of those who took the time to submit comments and suggestions. We've implemented some of your ideas (and corrections) already and will be rolling out even more site features for our savvy car shopping audience.
