The vehicle has been seized and it is in the process of being forensically examined.
Detective Superintendent Mark Baker said: “I want to make it completely clear that we need any information about this vehicle or the wider investigation as much as ever.
“Whatever information you have, and whether you are sure that it is the same vehicle or not, pass it on and we will assess its importance.”

Olivia’s family has paid tribute to her, describing her as a “unique, chatty, nosey little girl who broke the mould when she was born”.
They added: “Although her life was short, her personality certainly wasn’t and she lived it to the most she could, and would blow people away with her wit and kindness.”
The family has urged people to “do the right thing”, and said: “If anyone knows anything, now is the time to speak up. It is not about being a ‘snitch’ or a ‘grass’, it is about finding out who took our baby away from us.”
