The slowest it ever gets driven is down that track, weaving around the holes carefully. A week of freezing and thawing is not going to improve the track either.
The downside of an estate is the turbulence behind it when making progress on grubby roads that lifts the sh*te onto the back. By the time I had done 479 miles in it last Friday you could hardly see where the number plate went, never mind what was written on it!
