A bit hard for me to say as I started off in 2004 with the america, I put a lot of miles on it in 4 years then chucked it in for a new speedmaster in 2008. Then went back to a 2002 america and the the Thunderbird 1700 and now the Thunderbird sport. I suppose over the years I woud of put a few miles together. The america I have finally got everything I want for it and I will start to rebuild it.
