Persuade me to buy a Yaris!

[why?]

If your really have rough winter conditions you have to drive through, the Yaris as an only car is not the solution you are looking for.

I literally got my car stuck in maybe 6 inches of slush. I had to get out and push it a foot to get traction. I will admit the current tires are from down south, so probably were not made for dealing with snow. But my car got squirrely in any amount of snow.

No way should you go from a fully paid off vehicle to car payments if you only drive 20 miles a day. Do you fill your tank up more than once a week?

See if there is another subcompact that gets good gas mileage that you could afford to have both vehicles. Even 2007 model year Yaris can be had for 6 or 7 grand.

Echo's get great gas mileage as well and are even less expensive. Corrolla's the same.
