I had 'one of those drives' in the Jag this weekend. One of those drives when the sun is out, the winding country roads are dry, there's very little traffic about and everything seems to be working. It was great, and to think I was experiencing it in a car that has cost me just under £1000 to buy, tax, insure and repair made it even sweeter.

Indeed, the Jag seems a lot happier since colleague Lewis Kingston and I gave its throttle body a good spruce. It's still idling at around 1200rpm out of gear - thanks to a sticky throttle - but some more lubrication of the throttle cable should help out. More important, it doesn't stall or proceed to sling me unassisted down hills.

Another thing I have seen to recently is the radio. There's nothing wrong with the factory Jaguar unit's design and functionality - I quite like it, in fact. However, I've had real issues getting it to sync with the aerial, and three of the car's four speakers had given up the ghost.

So with the help of YouTube and a gentleman who skillfully took apart an X300's dash with a Phillips screwdriver in one hand and a shaking iPhone in the other, I began to dismantle mine. 

Out came the two screws holding the ashtray down, and with that removed, a piece of dividing trim comes away to reveal two wing bolts holding the veneer 'slope' down. Those off, and with the gear lever in neutral, the slope slips over the top and leaves six more screws to remove before the climate controls and radio housing can be lifted clear.
