This is a subject my friends and I have discussions about quite reguarly. There is no right or wrong answer, everybody is entited to their own opinion and everybody has their own views. I have spent ALOT of money on my car (SO FAR :readit:), in the space of 2 years that I have owned it.
I suppose I mod my car for a number of reasons. The number one being I'm a massive petrol head, so I love cars. But the main reason I'd say is because I love improving the car, and bringing it up to a standard that I fee is acceptable and necessary. Modding is good in the long run I feel because it keeps the love going, as opposed to you getting bored of the car.
The arguement I have is, say you buy a £10k car then spend £10k on it, your at £20k. But even then, I'd still have to mod the £20k car, unless I step onto the Gallardo LP560 level, I'll always tinker with cars. But then if I had gallardo papes, I'd be gettin a heffner twin turbo conversion lmfao.
Modding is very addictive and a very expensive game.
