Credit where credits due.
My 435d has just been in today for the EGR check and Brake fluid change (@42 months?).
Booked 4 weeks ago and got a 420d Conv 68 plate demo with hardly any miles on.
What surprised me was how nice my 435d was when I got it back, apart from the squealing brakes it didn't feel a day older, let alone feel like 3 1/2 years older than the new demo car, absolutely no bagginess anywhere.
Fantastic build quality.
