1. why go pro

maintenance
doesn't get skipped.
it gets lost.

1 in 3 drivers can't pay an unexpected repair bill. 35% admit they've skipped service they knew they needed. proactive maintenance is the answer. ddpc Pro is how you make sure proactive actually happens, every time.

or $14.99/mo.

2. the gap

the problem isn't that people don't care.

it's that the maintenance gets lost. the oil change you meant to schedule. the slight coolant drip you'd planned to watch. the check engine light that flickered once and hasn't come back. your garage already knows. you just don't have a place to keep what it's telling you.

3. the math

every $1 in preventive maintenance saves $3 to $8 in repair.

the auto-service industry has measured this enough times that the number is boring. consistently maintained vehicles post 40% to 60% lower repair costs year after year. the interesting part is that almost nobody captures it, because almost nobody tracks their own car well enough to actually get the savings.

ddpc Pro is $149 a year. one shop diagnostic you avoid pays for it with change.

all of this works on free ddpc too. you can log your own service, track your own fuel, keep your own part numbers. Pro is the difference between meaning to and actually doing it. you don't need the 8x end of the range for the math to work, you just need the log to stay current, the reminders to land on the right day, and the receipts to be where you left them.

4. what pro adds

free ddpc logs the work. pro makes sure you do.

the core app, free forever, gives you the garage. service log, fuel tracking, part numbers, build sheet, export anytime. Pro is the layer on top that turns having a log into actually using it. it reads what you've written, notices what's drifting, and tells you what's due before it becomes what's urgent.

proactive alerts

maintenance due, fuel anomalies, mileage milestones. on the day it matters, not three months after. free ddpc tracks. Pro tells you.

garage memory

Pro learns your vehicles and your service patterns. you stop re-answering the same questions every time you open the app.

instant recall

part numbers, service dates, torque specs. ask. get an answer that cites your own file. no scrolling, no guessing under the car.

6. continuity

every car has a previous owner.

half the mysteries in your engine bay right now came from the person who had the car before you. the receipt that's gone. the repair they meant to write down. the fluid that got topped off once with something that wasn't quite right.

when you keep a log, you're not just saving yourself money this year. you're writing the file the car carries with it. the next owner gets to skip the guesswork you had to do. their ownership starts healthier because yours was diligent.

and somewhere, the car you'll buy next is being driven by someone else right now. the question is whether they're keeping the file you'll inherit, or leaving you to reconstruct it.
