I don't really think age has much to do with it. I know several hot-rodders that are 60+. I'm 41 and have yet to own a completely stock vehicle for any length of time beyond what it took to save the bucks to modify it. There is no vehicle I can think of that can't stand some improvement. Note the word "improvement". I'm a firm believer in the old rule of engineering that "form follows function". If lowering your car limits it's use, you've failed. If modifying your motor means that it can't be driven, you've failed. If the new tires and wheels you bought look trick, but now rub if you carry anyone in the back seat, you've failed. Since I'm forced to be thrifty with my money, I need the things I do to be right the first time, and trust me it ain't easy. It involves tons of research, measuring until I'm blue in the face and shopping for the very best deal to make my car the best I can. It would be easier to simply scrape the grime off, rattle can paint the stock stuff and "restore" my car back the the assembly-line standards. But I'm after perfection and that means sacrificing my time, effort and money to build the best car I can.
