traded in our 2004 Ford Escape XLT with over 107,000 miles. served us well but we got our use out of it and was time for a new one after spending 400-800 dollars every couple of months on repairs.
ST's are a lot of fun. I currently have a '16 Fiesta ST in the garage.Traded in a '13 Silver ST Base with an aftermarket sound system put in. I was borderline offended with how bad the stock sound system was in the focus, but quickly fixed it after purchasing. Ended up going to the same dealer I bought my Focus from that I bought our '17 electric blue titanium.
I'll miss whipping the ST around.... but between the 2.0 in the FE and an '06 mustang GT (my wife somehow let me buy last summer) I think I'll survive!
