Overview
Triumph's four-seater V8 tourer was supposed to be a world beater but it stumbled early on due to the lack of devopment of the engine and build quality issues.
The great news is that all the teething troubles are now well known and a large proportion of surviving Stags have been put together properly, with specialist knowledge. That leaves us free to describe it as a stylish, strong and refined grand tourer that's relatively simple and cheap to maintain and it has one of the best exhaust notes ever!
The 3-speed Borg Warner auto and the manual/overdrive versions were produced in roughly equal numbers and each offers its own special characteristics. An excellent (but not cheap) conversion to upgrade the auto cars to 4-speed ZF boxes has proven very popular. Unlike some conversions (see below) this does enhance the value of a car.
Over the years a number of other engines have been substituted, mainly Rover V8s, Triumph straight sixes and Ford V6 Colognes. However, these conversions do adversely affect values and in recent times some cars have been converted back to Triumph V8 power.
Trade support is excellent, not only for parts but also companies with a wealth of experience in maintaining these cars, rebuilding engines etc.
