Having not mis-spent my youth, I know nothing about the inner workings of a motor car, other than how to clean spark plugs, where to put petrol, and how to meaningfully kick tyres.
However, I do recognise a rattling noise when I hear one.
Some time back I'd had to have some major work done to The Compact Royce; noise was coming from somewhere amongst the back wheels. There's a long metal rod inside the bit that connects the two back wheels that was making a noise on the right hand side, and it took a stonking €500 to fix.
Recently I heard a similar noise coming from the back left hand side, so I took it to my man for another €500's worth.
Luckily he found that in fact the new noise was coming from the front, and replaced the offending part for under €200 (a short rod with two rubber ends).
So, I now have a bonus of €300 burning a hole in my pocket.
The echo of my huge sign of relief is still bouncing around outdoors.
