The re-styling without the fog lights kicked off The VF2...question is, was there such a thing as a MY15 VF2??
Nah, if a car is released after about July in the year it's always the next year's "model year".
Papadoc, assuming I hadn't paid extra money to get a VF2 over a VF, it would in no way bother me if I had a VF instead of the VF2 I expected. However, you mention "paperwork", so if a dealer sold this to you as a VF2 & it DOES bother you, I think you've got grounds upon which to do something about it. Especially given that MY16 definitively describes VF2. Most likely, however, someone's accidentally written or transcribed a "16" rather than a "15" on whatever that paperwork is.
I once spent an hour on the 'phone talking to the Roads & Traffic Authority because I'd just bought an untouched factory car with a 2L engine whereas the registration papers said 2212cc. Although the RTA person didn't believe me, it turned out that their records were wrong for the spec-level of car I had, and they had the naturally-aspirated version's cubic-capacity on the turbo version of the car. If I wanted the paperwork changed I'd have to go to an engineering signatory & get a report ... it wasn't worth the hassle, and I figured the chance of it ever being a problem for me was low.
Typos & transcription errors happen all the time.
