As rymers said, it's all for fun. You live only once, so if it feels good, do it. We all have different needs and wants, and if you want something that'll get you to work 5 mins quicker or will put some Holdens to shame, the go for it, it's not gonna harm me.
My intention is to modify the LTD so it is the ultimate highway cruiser, it's already like that standard, but it can be better. I don't need more power, it's got enough, and fuel economy doesn't need to be worsened. I like my lights, my bars, my fridges, my little cow mods (it cheers me up and personalises my car, I mean who else has a cowprint rocker cover... OOPS I've said too much

) and not to mention the comfort factor, all important aspects of an excellent highway cruiser.
The bottom line is, if it doesn't harm me, then I don't care what people do to their cars. It makes them unique, gives me something different to look at and makes us all happy.
