Fantastic Simon! I think a 'new' car always takes some getting used to. the first few 100 km's you are very attentive to everything that might come loose or go wrong, and every 'new' noise triggers you. I remember when driving the Lambda to italy (after only 600 test km's), on the first day, al of a sudden there was a quite loud humming noise, while doing 90km's/hr. Thinking the trip was already over before it had begun in earnest, I stopped the car. The noise stayed, so it was not in the driveline. Also after killing the engine it stayed. (which was a great relief). And then (only then...) it came to me: it was the horn... Turned out for some reason the metal wired sensor 'cable' of the period temp gauge I installed touched the wire of the horn where it exited the steering box...and the trip was continued....but it was a frightening moment!
