I have owned my 96 xj6 vdp for nearly 20 yrs now. Lately she is costing too much in repairs but the x300 has been such a reliable car and I have always wondered about the V12 engine I am looking at purchasing a very nice and clean 122000km 1996 version of one. What should I be looking for in terms of trouble areas and are they as good of a machine as the xj6 has been? Any tips will be of great assistance. Thx J.
