With 44 drivers lining up for qualifying, Holley put in a great performance to qualify 13th in her Gunn TS7 car and during the race managed to propel herself up the order, overtaking former champion Nick Bates along the way.
She crossed the line on the tail of the sixth placed driver, another former champion, Martin Ellis.
‘I found my first race experience very exciting but also overwhelming at the same time,’ said Holley.
‘My test session on Thursday had gone well and the car felt good throughout; going into my first ever qualifying session was quite exciting but I knew that I had to keep calm and composed in order to try to do a good job.
‘I was happy with 13th on the grid and sitting lined up in my grid position with cars surrounding me was indescribable – my heart was beating and I could almost feel the adrenaline.
My start was sufficient enough to move me up a few places by the first corner and from there I decided it was time to show what I could do.
‘I started to overtake and found myself in the middle of a great battle with the four cars around me, I was feeling really good and had complete confidence in my car.
Crossing the finishing line was fantastic – no mistakes and lap times equalling the top runners.’ Team owner Tim Matthews added: ‘There are loads of drivers in each race and the front ten are extremely quick, very experienced and undoubtedly tough racers.
For Christina to finish seventh on the British GP track in only her first ever race is outstanding.’ Holley’s next race is at Oulton Park on 22 September.
