I write a deeply satisfied man, from a camp bed in a room next to Silverstone's GP circuit, where the Britcar 24h is being contested (the circuit, not the room).

Three journalist colleagues and I are driving a near-production Mazda MX5 prepared by team Jota racing, and I am a happy camper because 1) the car is delightful to drive and 2) it is currently running, with Autocar contributor Andrew Frankel at the wheel, in 23rd place overall. Which, given it qualified 49th and there are GT2 Ferrari 430s and Porsche 911s in the field of more than 55 cars, is remarkable.

We have to thank the car's exceptional economy and ease on its tyres. I drove the first two hours and overtook just one car, but by staying out of trouble managed to come in in 31st place.

The plan remains to stay out of trouble, be kind on the mechanicals (I am making just six gearchanges per lap, shifting from fourth to third three times), and see how we get on. I have a graveyard driving shift at about 1am. Twitter updates after that, @matty_prior.
