While we're discussing degradation and the chart shown by Tessie, I would like to take the opportunity to request a time-based degradation chart. Yeah, you would have to let users manually enter their car's manufacture date, or Tessie could probably get away with just using the connection date for cars connected to Tessie within the first 500 miles or so, but as someone who puts very little miles on my car, it would be a lot more useful to me. The current degradation by mileage chart makes my 14 month old car with 8,000 miles look absolutely awful.
