Strangely enough, I managed to stay calm (for two weeks!) up until a friend picked me up to go to the dealers. Then on the journey there, my heart started palpitating and the instant I saw a black Golf with a red stripe on the forecourt, I knew it was my car despite there being two other black GTIs there!
Take a camera with you - that's the one thing I wish I had done because, although it was raining, I took some pics with my K800i and it doesn't do it justice.
