Heat is the dominant Chandler wear factor
Chandler records 100°F+ days from May through September — sometimes 110°F+. That timeline does specific things to cars: AC compressors fail at year 8-10, batteries die in 2-3 years instead of 5, dashboard plastics warp and crack, paint and clearcoat oxidize. By year 12 the dollar repair bills justify junking even on otherwise mechanically sound cars.
No salt, no rust. The drivetrain side stays remarkably normal — engines and transmissions outlive the body and electronics. Most Chandler junk-car offers are limited by AC, electronics, and consumables rather than mechanical death.
Long-park failures and the snowbird factor
Arizona's snowbird and retiree communities park second cars for months at a time, which creates the exact failure pattern desert summers reward: dead batteries, dry-rotted tires, gummed fuel systems, AC compressors that bind on first start. We see hundreds of these every summer.
Catalytic-converter theft tightened in Arizona 2022-2024. Documented cores are valuable; cars without a catalytic converter see a reduced offer. We still buy.
