DIY maintenance proof

How To Prove DIY Car Maintenance

DIY work can be valuable, but buyers and shops still need context. The best proof is a clear record that shows what was done, when it was done, which parts were used, and what evidence supports it.

Resale proof

Write down the basics every time

A strong DIY record includes date, odometer, service name, parts used, cost, time spent, notes, and whether a follow-up reminder was created.

Attach evidence where it matters

Photos, receipts, part numbers, torque notes, fluid specs, and before/after observations help explain work that does not have a shop invoice.

Share the record without giving up control

When selling the vehicle, a read-only Wrenzo buyer packet can show owner-performed work, receipts, photos, and notes without letting the recipient edit your saved Garage.
