Believe it or not, people looking for 69 mach's to drive and enjoy are looking for the small block mach's. They're affordable, great in traffic and exceptional on gas mileage (my 351W 2V gets 18 MPG).
And when it comes to resale value, they will hold their value. Good Luck and welcome to the 69 mach world!!
BTW, the 69 mach in my signature is my wifes and it's been in her Family since 1970. Take a look at "My Garage"
