Triumph Stag

Triumph Stag The Triumph Stag sold only 2871 cars during the period when it was on sell between 1971 and 1973 in America. The car had a lot of assembly faults which was causing the company a lot of headache. 

The car had a lot to offer but this 2+2 by Giovanni Michelotti was a problem child from the day it was launched.  The engine designed by Lewis Dawtrey was only ever used to power the Stag. Triumph was receiving warranty claims left, right and center due to overheating, cylinder gasket failure , slipping timing chains , water pump failures etc. 

A major component that required no work was the Stag's unusual (for an open Triumph) monocoque body. As built, that open 2+2 body incorporated double-walled sills and pockets of fiberglass in polyethylene envelopes to absorb noise and control heat. The Stag's independent front and rear suspensions were mounted on subframes, and adding rigidity and safety was the car's trademark "padded steel tri-form arch," its T-bar roll cage.

Pros

Handsome Italian looks, comfortable cabin
Fine performance when sorted
Great support from Stag clubs and specialists

Cons

Having to make it reliable, if not already sorted
Typical vintage convertible rust issues
