 Independent Engineer's Reports on my Jaguar S-Type - From the AA (UK) and TCS (Switzerland)

Independent Reports - Written reports on my S-Type from professional Motoring Organisations.

My Jaguar S-Type has been independently tested by the professional and respected Motoring Organisations of the AA in the UK (since 1905) using fully equipped Garage facilities (AA website) and the TCS (Travel Club Switzerland since 1896) at their modern test centre in Aarau (TCS website). Both of these organisations commented on the lurching ZF Gearbox and heat damaged brakes on my S-Type. Excerpts from these written reports are shown below (Deutsch unten ).
