If the Ford Mustang was such a great car, why didn't Ford keep the original 1965 design?
In 1965 the Mustang was an affordable sporty car with performance if you had the 289 c.i package. Over the next years they evolved and were upsized to handle the power of the larger engines(302, 351,390 and 428). The original short wheelbase and 14 inch tire car could not handle the increase in horse power. In 1969 it was called a Mach 1, not a Mach 11. Shelby Cobra's, or at least the original ones built by Carroll Shelbey had a 427 side oiler engine. The last true mustang was built in 1970 as after that year they were detuned for insurance and emmission concerns. The Mustangs of the late 70's and early 80's had to be the ugliest car ever produced. The new Mustangs, even with their upgrades and comforts are just that-new. They will never be worth anything as a collectable and depreciate like all other new cars. Find a 1965-1970 Mustang, restore it, both for the investment and for the pleasure of owning a real car.
