I basically have the min insurance (can't afford much else), I have it taken out in monthly installments...much easier to budget that way.
Focus should be good on gas, much easier than feeding a thirsty 6 cylinder.
Set some money aside and expect the unexpected...and to do a few minor repairs the first year if this car wasn't used much/sat awhile??
My truck basically sat for 10+ years only going back & forth to the P.O. and bank now and then so had to have tires right off, not because they were worn out but because of dry rot...battery, wiper blades, tune up, etc. A bunch of small stuff the first year...abs sensor, wipers dying every rain storm (thankfully an easy fix)...this one (Focus) sounds newer so hopefully won't have any problems.
