Alright, so I have been given the family's car since 1993. It is a Safari Minivan with 150k miles on it, it's all wheel drive, and the interior and everything was custom and upgraded and is super comfortable. It's got mood lights, the chairs fold into a bed electrically by a switch but that is currently broken, and it has an old TV in it that doesn't get a signal of course but it never really worked in the first place. Besides fixing the chairs, what else could I do to my van to upgrade it? I was thinking of putting a new sound system in and getting the TV to work but I don't know how well a TV would work in a moving car on the highway, ya know? Anyone do it before? I love this car and it is beautiful. I don't want to upgrade how it looks, but just make it functional as all can be in the inside and make it kind of like a fun car.
