The Alvis TC 108G is a British sports car made by Alvis Cars between 1956 and 1958. Coachbuilders Graber of Switzerland had produced a number of bodies for the TC21 which were much more modern than the standard offerings built for Alvis by Mulliners (Birmingham).

1957 Graber Alvis TC 108G with Willowbrook body
It was therefore decided to make the Graber style (car at the Paris Motor Show in October 1955) the basis of a new model and the rights were purchased, resulting in the TC 108G. A contract to build the new bodies was placed with bus builder Willowbrook of Loughborough. The car was available only as a two-door, four-seater saloon, made by moulding metal around a traditional wooden frame. Graber later resumed production - probably at the request of Alvis - but changed the body shape.

The Willowbrook body proved too expensive and few were sold. The deal was terminated and a new contract was made with Park Ward Alvis after he purchased the drawings, moulds etc. from Graber. The new car was designated the TD21 and entered production in October 1958.

The 2993 cc engine was slightly uprated to produce 104 bhp (78 kW) at 4.000 rpm by modifying the cylinder head and fitting twin SU carburettors. Suspension was the same as the TC 21, independent at the front by coil springs and leaf springs at the rear.

This car has been almost completely restored in a period of more than 3 years. A beautiful photo book has been made of this restoration in which everything can be seen of this extensive restoration. This very distinguished car is more beautiful than the standard models that came after it. The entire history of the car is documented and can be purchased at Red Triangle in England. Here you can see everything that has happened to this hand-built car. Furthermore, there is a valuation report and some articles. It drives very smoothly due to the six-cylinder engine, shifts and steers very well. This is really a car for the connoisseur who is not looking for a Rolls Royce or Bentley but wants to stay a bit under the radar but is still looking for a class car.
