You do what u want to ur car. After all u obviously like cars more than the "it gets me from a to b" type. I love to pesonalise my cars and am always looking for the next mod I can do myself. The fact that ur on a forum based CAR website says that u like cars. Do what u like doing, while we can still legally modify our cars. Looks like ur going down the tastefuly modified route.
I sold my vtr over a year ago, but I still love it. I spent over £5K
on it, which I got brand new for £10K. I had it for nearly 4 years. The book price was £3,400, but I got £5,000 for it. Its not about the money though, it should be fun modifying/personalising it. Most people say u de-value ur car modifing it, but someone will appreciate ur mods.
Stick at it. Ur doing a great job.
