Think you meant Focus ST under 50K and Fiesta ST
I sat in my first Stinger the other day....my brothers new one replacing his 08 FG G6ET. Didn't need the comparison to the FG to make the Stingers cabin floor me, what a awesome place to be. And with the optional exhaust? Sounds great even at idle and legal to boot. And boot? <100km and a throttle prod and SHOVE. Awesome car, amazing for the $.
(actually not replacing the FG sorry, but FG moves to backup duties, <100000km and still a great drive)
