For me it's the raw driving of no bullshit electronics like power steering, abs, etc etc. for that sort of power and fun you need to spend a lot more on something like a kit car. the scarcity of the car is something i like and the simplicity of them as a whole.
new cars are shite in my opinion and i hate the fact everyone has the same cars, i'd hate to buy a civic type R knowing that if i drove around i could see another 5 exactly the same bought by sheep who dont know how to make a choice on their own. mini's are a good example of this.
I like how they are perfectly simple inside, 3 heater settings and thats it, not hundreds of choices and directions which are just pointless.... a bit like having all the sky channels money can buy but you never watch anything because you spend all your time looking for something better. sometimes....less is more.....
