Re: 2007 Grand Scenic Haynes manual.
To give you a comparison, I have a 55 plate Laguna registered 2006 and I have a haynes manual (up to 54 reg) which also says it doesn't cover phase II Lagunas (Which is my car)
BUT, everything mentioned in the manual is practically in the same place 99% of the time. All the procedures are the same as it would be anyway.
Currently in Phil C's garage:
