Prepare for next season

Fleets buy on a yearly rhythm. Know what they'll need next so you can stock up, set prices and plan promotions before demand arrives.

Now · September to October

Route start

Buses are rolling. Long dark mornings put the focus on being seen.

  • Headlights, marker and stop-arm lamps replaced
  • Mirrors and glass checked after summer heat
  • Door and body hardware tested under daily use
  • Alternators and charging systems verified

Parts fleets buy for this season - see current prices:

Coming next · November to January

Cold-weather prep

Cold starts, salt and ice. What fails in January is usually bought now.

  • Batteries, block heaters and charging parts
  • Heaters, defrosters and anti-icing parts
  • Wiper blades and washer systems
  • Oil, fuel and air filters changed for the cold

Demand signals

Searches and clicks to supplier sites, per part and category - always labeled as interest, never as sales.

API & MCP access

Pull part-level prices, stock and demand into your own tools on a schedule.

Privacy by design

No buyer names, uploads or private lists are ever shared. Small groups are hidden.
