 Biggest mistake I ever made, was buying a Ford Focus. Its used up 17 tires in 80000 km.  3 of the tires were legit, due to nails found.  But the remaining were due to bad alignment, crappy suspension, and dust/dirt in rims. I will never buy a Ford product again. Also, the amount of dust that gets through the stripping around the doors is insane. My car is always filthy but I was told thats just a Ford Focus, its how they're made. Its fun to drive and good on gas, but its the biggest mistake I have ever purchased.
