Hi - I am getting rid of Z4 Coupe and buying a 2005 Carrera or Carrera S coupe in 6 weeks, and having a real problem deciding whether to go Porsche Official or one of the specialists..budget is £36-40k, don't mind paying for official but put off by their (I'm based in London) labour rates etc - do about 5k miles a year, planning to keep 997 for 2 yrs, so maybe not too much of an issue but prefer their warranty. Has anyone had any experience with either that can give me some advice. Many thanks
