Can I say I hate you!!!!
I love that car and so desperately wanted to buy it, but didn't have the dollars at the time. Well done on a fantastic purchase. I haven't seen another 04 red Mach 1 in Oz, but there is a black one on car sales for $70k - not sure if 03 or 04 though.
As a side, I am pretty sure that they all came with the shaker.
Well done, great buy and welcome to a lifetime of fun.
