its a question everyone will answer differently and there is no logical explanation other than because i want to and i can.
its the same as asking why some ESCOS owners spend thousands on a car that at the end of the day is still a ford escort when for the same kind of money they could have a car with a more prestigious badge or asking the buffys why they buy a decent car only to garage it and trailor it to shows... the reasons are the same... because we can, we want to !!

A 400bhp rwd car makes no more sence than a 400bhp fwd car, neither make any more sence than buying a range rover to climb the near vertical curbs we have in London.... but do they really need to be justified ?
