Hi mate. There is some mystery over the actual numbers of each VTiS model made. The logbook should have made it easy to identify a genuine one, but unfortunately even that is a minefield as Honda dealerships made mistakes with them when registering the car with the UK DVLA. Some have VTiS on the logbook, some just state model as VTi. The only parts that were unique to the VTiS were drivers side floor mat which had the VTiS logo on it (the other 3 mats were just standard) the gear knob (alloy and engraved in the early VTiS, silver plastic/black leather with "VTiS" in black on it for the post 1997 ones) and the alloys (again, these differed so early ones got 15" Speedline Chronos wheels, later ones got the same as the ones in your photos which are 15" Speedline "fans"). The body kit was available in the accessory catalogue, but was standard on the VTiS. The "mid spoiler" on the aerodeck was also an accessory option. The other thing that marked out the VTiS was the pirates black paint. All VTiS came in pirates black only, so any you see that don't have pirates black are 100% not a genuine VTiS. The Aerodeck ones are a lot rarer as most were the mb6 5 door hatch.
Hope this helps a little.
