This little yellow coupe is a '66 and it shows what can be done starting with a six-cylinder car as a basis. This mildly modified Mustang has a hopped up engine, five-lug wheels, and all the external details looking good. The K-style "high performance" emblem highlights the number 200. The upside to the six-cylinder cars is inexpensive initial cost and economical operation. Parts availability for the inline engine is not nearly as great as for the 289, but there are a small group of die-hard parts companies still supporting them. We think the vinyl top is always a good-looking option on this body style.
