I have been looking at a Vectra 1.9 Elite, and it was advertised as a 150PS CDTI. It has the red "TI" on the badge. I just looked up the insurance on confused.com, and they have that reg plate as a 120PS engine. Looking at Parkers, ther is no 120PS Elite. DVLC have that reg plate as 159g/km which matches none of the figures on Parkers (the various trims come up as either 154 or 157g/km) How can I tell if it is a 120 or 150PS? I viewed a sample HPI report on their website, and it mentions the trim, but not the engine output. Bob
