The second year of Hot Wheels features 24 new cars and many of the first year cars are continued.  Of the 1968's still being produced the first to be dropped from the line-up were the Custom Camaro, Custom Cougar & Custom Mustang.  That is why they are so hard to find today especially in like new condition.  The 1969's featured the new series names "The Classics", "Grand Prix", and the "European series". 
All models were made in Hong Kong
