Average repair costs: $325.38
Index rating: 0.96
Despite having only one car among the Top 100 -- the 2011 Chrysler 300c at No. 73 -- and watching repair costs jump from $287 in 2012, Chrysler gets high marks by keeping costs low. It top issue is a wonky gas cap that costs 5 cents to replace and its costliest repair -- that pesky catalytic converter that needs replacement in 6.45% of all cars at $1,119 a pop -- ranks No. 5 beneath repairs that each cost $320 or less. Looking good, Chrysler.
