It’s my “first” and I need help…

I intend to go from Wuppertal to Korbach in Hesse next Saturday, 01.10.2011, in order to see or buy a Jaguar XJ 8 4.2 V8 – Bauj. 2004 – 100 000km. I have no experience with Jaguar and it is therefore “my first”…. I would like to see someone with appropriate “expert knowledge” about the Jaguar and/or especially about this model type, who would be at my side with “Council and Action” or possibly also imagine. could go with me (against reimbursement) together to Korbach in order to spare me disappointments or a “mispurchase”. Otherwise I would also perhaps already be served with tips and experience values, on what I should pay attention to when buying or what one has to know about this model! I would be very happy about corresponding contacts. Dear greetings from Wuppertal, Klaus
