Keeping a 1967 beetle at original value
I have a 1967 Beetle. I want to put in modern(or more modern) seat belts. Will
this hurt the value of the car? Are there other modifications I can make that will
also not hurt the value?
Unless it's a really immaculate and perfect original car, I don't think that changing the seat belts will hurt the value. Beetles aren't really that valuable anyway. As long as you keep the original parts in storage, any part that you can change by bolting them on and not cutting up any original parts are fine. When you sell the car, you can put the original parts back or offer them to the buyer. The only modifications which will ruin the car's value are things which can't be easily reversed, like cutting a hole in the dash for a modern radio. Changing wheels or even engines is fine, as it can be undone.
Watch any auction and see how much aircooled VW's are bringing. Original cars are usually worth more. Like Mark said keep any parts you replace and you will be fine. A nice older VW is a good investment now. Again don't cut it up or do body mods ...Seatbelts should be fine. The most important thing is have fun with your bug. Do what makes you happy if you plan to keep the car. For reliability things like alternators and electronic ignition are nice (eliminate your points). Those will make the car more reliable and should not affect the value.
Bolt on changes can be easily reversed so don't worry about it.
