I bought my 2006 Focus ZX3 (2.0L Duratec) 5MT in Dec 2010 with around 93,000 miles on it. When I bought it I had the throttle body cleaned, and driver side seat belt replaced by the dealer.
Since then I had the 100,000 miles maintenance done (I think it's just coolant and spark plugs), trans oil changed, oil changes every 3k miles (Motorcraft 5w20 synth. blend). That's about it, it's been solid and currently has just under 112,000 miles, I figure I should be somewhere around 120,000 miles when I'm ready to trade it in next year.
