303 Fabric Guard or Scotch Gard Protector, both smell a little musky if you can handle that for a the day or 2 they settle in, you can also some high end stuff from the UK called G Techniq I1 but that's if you really love your car.
When I bought my car, it came with the iBEX protection system. I in general do not care about this and would avoid as much chemicals in the car as possible. Does anyone know if this type of stuff actually works? I never get rid of a car b/c its fabrics looks old so I think all of this is a big waste of money.
