Coombs Modifications

Coombs Mk2s


The Jaguar 3.4 and 3.8 litre Mark II cars are fast, safe and complete in standard form, but we are able to offer discerning motorists even better performance and handling resulting in virtually a full 5 seater Grand Touring car at moderate cost.

Modifications can be effected on either new or used cars and one of the significant points is that the cars still retain their outstanding flexibility.

Experience gained through many years of racing and servicing these cars is inbuilt in the modifications offered and we shall be pleased to discuss customers' individual requirements and arrange for a demonstration in a fully modified car.
