Not everyone wants a lighter car, since heavier survives a collision better. When I got my first car, my dad advised me to get a nice heavy one, in conjunction with a quick recap of momentum mathematics on why the heavier vehicle has more survivability in a collision. A while back, a young, female friend of mine who drove a surprisingly large SUV, said that her dad bought it for her so that she would be safe.

So, not everyone is going to see this as a positive selling point...
