Martin - Thank you soooo much for the detailed instructions. I will DEFINITELY ask my mechanic what he plans on doing to the car (he is actually going to see the car today if it is still for sale) if I do purchase it. This is great info for any used car I will buy going forward and I will advise my daughters to do the same. I love cleaning the interior of cars so I will be following your instructions.
Thanks to all. Hopefully you won't hear from me again, but don't bet on it

Information is power and I have been feeling powerless when it comes to cars but that's about to change at least slightly
