When I park and get out of my car I always put my hand on my door edge and if there's not much room my hand touches the car next to me so it's not metal against metal.
My wife has MSA and uses a wheelchair so I was pleased when we were give a blue badge which enabled us to use the disabled bays.
We parked in a Tesco's disabled bay shortly after, I thought this is great, I could open the doors to their full extent and there was still loads of room between us and the next car. No more searching for a safe place to park
When we came back to the car someone had scraped their car against mine and damaged the rear door and bodywork. Of course the car had long gone although I knew it was a white car looking at my damage.
How much room do you need.........I just give in sometimes
On the plus side I took it to a bodyshop and they said to put filler in the bodywork, respray and blend in was about £800 so I went to Chipsaway and was quoted £270 for the same.
Crossed my fingers and tried Chipsaway and to their credit they did a perfect job you just couldn't see the repair or where it was blended in.
