Moll, you are now in the 4x4 owners club. We have a right....no a duty to bash other cars out of our way Just reverse slowly, when you hear a crunch....keep going.
Personally, I would never buy a pup from untested parents whether it was a terrier, lurcher, gundog, sheepdog etc etc. Its hard enough getting a good 'un without making life harder.
I have a flick through every now and then when i'm in the papershop. There is usually the odd interesting article, I missed out on the GSD lurcher article last week I used to love the old shooting news, nowdays the magazine only seems to print hunting articles that are "safe". The only mag I get now is EDRD.
