"The average Porsche leaves the dealership with options adding about 20 per cent to its price"
Curious comment, happens with most new cars these days (both examples here 20% or more).
Base Accord - 24,790; Loaded - 35,390; somewhere in the middle EX-L model just shy of $30k
Base Focus - 15,999; Loaded - 25,099; desirable SE model for the masses easily $19k
I could go all day...
