so. what do you drive?
every car's story has two halves.
the public half is already written: recalls, owner complaints, real running costs. ddpc keeps 1,713,891 owner complaints indexed across 36,214 year/make/model profiles, free to read, no account needed.
the other half only you can write: what you paid, what you fixed, what you caught early, what you changed. ddpc is the vehicle file that keeps both halves together, owned by you, not by the industry that sells your car's history back to you.
look any car up first.
specs, reliability scores, known issues, and an honest buyer's brief for over 125,000 year, make, and model combinations. shopping for a used car or checking on your own, the file is already waiting.
