Your books — one book per car
“Start an empty book” removes the SAMPLE book for good and leaves one blank book ready for a car you name yourself. The owner’s real books are his to start, empty — no real car is preloaded here.

BUILD SHEET opens one clean printable page for the selected car — parts list, service history, and totals. EXPORT JSON downloads this car’s whole book as a JSON file you can keep or re-import later by hand.
