Touch wood mine has been really reliable. You just have to remember there an old car with ice age technology and design. The biggest issue ive had with mine is the bodywork but then again if i didnt get robbed twice and went to a proper bodyshop in the first place i would of been ok.

I used to use mine everyday for 5 to 6 years and it never let me down. There like most old cars they need a bit more tlc compared to modern cars.

You will also get more looks in the sierra than you will the focus.
