i was at donnington today and it rained all day. Certainly makes you become a smoother driver..... No Ferraris but there was a nice Grey VXR220 Turbo. Very nice track and extremely challenging in the wet.
I hope you had some better weather than we had. It was a little slippery yesterday! There was plenty of valuable cars including a Ferrari 458, race spec Aston vantage, BMW M3 Brit car, modified r35 skylines... I'd say more than 50% were dedicated race cars yesterday, even the M3 CSL turned up on a trailer.
I take my hat off for you. The weather on your vids looked horrendous.
It was. I went out for some passenger laps in one of the caterham r300's with no doors, roof or windscreen. My waterproof trousers and coat arent actually waterproof - I got soaked to the skin, literally! It was sooo worth it though. The caterhams can slide for England - huge fun in the wet as long as you don't mind getting wet yourself and amazingly grippy.
