I grew up among cars. Both professionally, as well as after work hours, my activities are largely connected to cars.
From a very young age, we went to watch car races with our parents. Later I started to take pictures at these races and so we continued to look for various events.
The nice thing is that the cars you have seen driving in the past are now returning to classic events and so they bring you back to thoughts of the past.
The current street- and racecars are getting more boring every year and the classic events are the ideal way to counter this.
