Ive just bought a 2005 (05) Vectra 3.0 CDTI Elite (Auto) and im confused about the facelift and power change dates???? Im not sure if mine is the 177 bhp or the 180 odd bhp model how do I tell??

Also, i'm thinking about getting it chipped can anyone advise me on what is available for chipping and tuning in the north east and what are the pros and cons

I had a 330ci BMW before the Vectra and im loving the Vectra more happy motoring to you all
