Triumph Stag service history FAQs
What should a Triumph Stag service history show?
A Triumph Stag with full service history should show regular servicing every 3,000 miles or 6 months. The record should include oil and filter changes at every visit, plus periodic items like coolant flush and timing chain service. Any gaps, especially after year 3 when the warranty expires, are a red flag.
How many services should a 10-year-old Triumph Stag have had?
Based on Triumph's recommended interval of 3,000 miles or 6 months, a 10-year-old Triumph Stag should have at least 20 services on record. Fewer than that suggests missed maintenance.
What does a gap in Triumph Stag service history mean?
A gap means the car wasn't serviced at a franchised dealer during that period. It may have been serviced at an independent garage (which won't appear in dealer records), or it may not have been serviced at all. Either way, it reduces the car's value and increases the risk of hidden problems.
