this i know ALOT about as i am a qualified "business manager/finance manager".
the paint protection they offer for 3-400 bucks cost the dealer about 20 dollars
and an hours labour. the fabric spray atomizer is not much better than scotch guard
even tho they will tell you it is.
imo the undercoat and rust inhibiter are a good thing...but are very expensive.
propack costs 1200.00 for you (paint,fabric, undercoat and rust inhibitor)
it costs the dealer about 75.00 for product and 4 hours of someones labour.
1000 profit on a 200 cost

not bad for the dealer eh?
