Summers here bring about 25 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 108 nights a year. Cold is when a weak battery finally fails, because a cold engine takes more power to turn over.

About 46 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 Plainfield is 23 minutes each way, and 75% of workers drive there alone.
