What a build timeline actually is, how to log a modification properly, and how Verified Installer confirmation turns a claim into a trust signal.
A build timeline is the running history of every modification you've logged against a vehicle, in the order you made them, each with its own photos, cost, and category. It's the core of a garage profile on The Car Scene: other members, and any future buyer, can see exactly what's been done to the car and when, not just what it looks like today.
From your vehicle's page, add a modification with a category (engine, suspension, exterior, and so on), a title, and as much detail as you have: description, supplier, cost, and the date it was fitted. Photos matter more than any other field here, since they're what turns a line of text into something people actually engage with and react to.
If a real garage or tuner fitted the part, you can link the modification to their profile in the Tuner & Garage Directory. That business gets a one-tap email confirmation link, no account needed, and once they confirm, the modification shows a Verified badge, a real trust signal backed by an audit trail rather than a self-asserted claim.
Other members can react to a modification (Fire, Goals, Clean, Mental, RIP Wallet) the same way they can react to your vehicle profile as a whole. It's a lightweight way for the community to acknowledge a build without needing to leave a full comment.
