Well Biju, I guess this is where you and I definitely differ. I am 100% with you when you say you have the urge to mod stuff. But to me, while the modding is part of the fun, I get an extreme amount of satisfaction in the completion of the project, and my putting it to use. I don't feel bored with my VX, and when it is "done" I can only imagine the feeling I have now, will get even stronger (that feeling being that every time I look at my VX I think to myself, "damn, that sh1t looks mean!")
In your case, you created what I think is the best audio system mod I have ever seen with my own eyes, so how could you not want to keep your VX for many years and enjoy the fruits of your labor? I can safely say that I am about 75% done with the things I would like to do to my VX. And when I am done, I will feel happy and satisfied that my ride is exactly the way I want it, and can do all the things I want it to. And then you just sit back, crack open an ice cold Blue Moon, and revel in your accomplishments and the fact that it is YOURS, and yours alone.
And then there is the simple fact that the VehiCROSS is one of, if not the coolest SUV ever produced. There are loads of vehicles I would love to test out, and possibly own, but not in exchange for my beloved Ebony.
So like Bim said, just take on another project, and enjoy your beautiful, pristine Proton that makes us all jealous when we see it.
After my VX is "done", I will be moving on to a new project (a 1976 Aussie Ford Falcon) which will eventually get finished as well, and will hopefully be a garage mate for my VX for many, many years. After that...the list goes on!
