Pre-Purchase Inspection Checklist (579 Focus)

• Aftertreatment health: Scan for active codes; check DPF/DOC ash load, SCR/NOx sensors, regen history.
  
  
• Fuel economy baseline: Confirm axle ratio vs tire size; verify cruise RPM at 100–105 km/h.
  
  
• AMT specifics: Review clutch wear index, calibration history, software updates, and shift quality.
  
  
• Cooling system: Pressure test, inspect charge-air cooler and hoses.
  
  
• Suspension & brakes: Airbags, bushings, even lining thickness; slack adjusters within spec.
  
  
• Electrical & sleeper: Battery load test, alternator output, bunk HVAC, moisture/seal integrity.
  
  

If you plan preventive work post-purchase, consider Truck Repair Financing to spread initial costs.

What Drives Price on a Used 579

• Model year & emissions history (clean aftertreatment = fewer surprises)
  
  
• Kilometres vs. hours (idling profile matters)
  
  
• Service records (oil intervals, valve sets, DPF services)
  
  
• Cab/sleeper spec & driver tech (comfort and safety packages)
  
  
• Tires & brakes on delivery (credit for replacements or fresh components)

Case Study: Mississauga Carrier Adds a 579, Protects Liquidity

Profile: 8-truck GTA fleet; food-grade lanes GTA ↔ Midwest
Challenge: Add one 579 before peak season without tying up cash needed for fuel and drivers.
Approach: Compared 60-month loan vs 60-month lease with 10% buyout using the calculator. The lease reduced monthly obligations ~10–12% versus the loan. A small sale-leaseback on an older tractor funded day-one tires and a DPF service.
Outcome: Delivery in under two weeks, on-time tender wins, and no payroll pressure.
