Just more things to go wrong eventually in my opinion. All these cars are ok when new but in the future the second hand market could end up paying big bucks to replace failing technology I fear.
Mine is agreed value with Coops for Β£25k. Deffo needs a paint job and more. Mine doesn't look as clean as yours either so you deffo need to up it to Β£30k.
I also heard that from a friend who was a tanker driver!
I use super from Shell/Esso/Tesco or wherever else i can get it although have been told by my tuner (my other half :D) that I can just use normal 95ron ... prefer the super though (just in case).
