Ditto, just my car are a little younger, but i have put 2 screws in the center console to mount my flashlight, and i have used the dremel too on the center console to be able to route a wire.
Even if i was to sell my little POS car one day the buyer will not be looking at little things like that, and besides if i am going to sell it then it will probably be in a deal on a new car, in which case dealers might pay upwards of 30.000 Kr for a wreck, just like the Fiat punto i traded in when i got the Suzuki.
But even if i sold to a person i am sure that person will just be looking for a cheap car, that have 2 years on it before the last inspection it will fail unless you pour a lot of money into the wreck on wheels.
