Not to sound like a pr*ck or anything but there is no way that was black ice. 6.5c and not a trace of any snow/ice on any of your pictures.
Either way I hope it gets settled, and like you said, time to move up in the car world!
Yeah I think it's called black ice because it's hard to see...I didn't show it any of the previous photos. It was the only bit on a mile long country lane, just in a crappy place.
Anyway here is the photo I took, I have labelled it for you as well. It is hard to see but it's there. The paramedic nearly slid on it when he came bombing round the corner. I have an HD video of it which shows it better but I can't be bother to upload it.
I went and test drove the new Audi A1 on Saturday. I'm just going to get a crapmobile for a little while, I'm looking for new job at the moment as my current one is rubbish and I don't get paid enough for what I do, also my boss doesn't maintain the lane where our office is, so it has massive potholes which I hated with my supert's and a muddy drive which always ended up in muddy floor mats. No way I'm driving a new A1 down there each day and getting mud all in my new car. When I get new job I'll be placing an order.
The crapmobile will get used for the next 5 months until my insurance is used up, A1 has a 3/4 month waiting list anyway.
