Summers here bring about 26 days at 90°F or hotter. That is enough to finish off a tired battery or a weak AC compressor, so get both checked in spring rather than on the first hot day.

Lows drop to freezing on about 110 nights a year. Cold is when a weak battery finally fails, because a cold engine takes more power to turn over. Decatur averages 14 inches of snow, and road salt eats brake lines, exhaust and the underside of the car. Rinse the underbody through the winter and have the brake lines looked at whenever the car is up on a lift.

About 40 inches of rain fall in a year. Worn tires lose grip on wet roads well before they look bald, and streaky wipers are a cheap fix worth doing before the wet season, not during it.

The average commute in Decatur is 18 minutes each way, and 78% of workers drive there alone. 12% of households have no car at all, which is part of why mechanics who come to you do well here.
