You can get adblue at almost all filling stations or Tesco supermarket.
These trading estate car parks with paid parking, i just dont go there now.
I was sent a parking charge for parking and a photo was sent showing my car on just black tarmac so i asked where were the parking bay lines as this photo could have been anywhere. They had to wave the charge as i had not parked in the car park at all. I drove through it just looking for a space and drove out again.
Its only £100 Jerry, now what could you have bought with that ? a weeks shopping, a very nice dinner out, 2 pairs of Sketcher slip on trainers but now you just have to suffer.
I recently paid £100 for my course to teach me not to speed in the 40mph limit. I hate losing £100 and have nothing for it.
