I had that with a car, it was in storage in the garage (wasn’t driving it because it was winter, it is a convertible, a camry solara) and rodents invaded the garage. Chewed the wiring, shorted out fuel injectors, ECU went…cost like 15 k to fix (insurance paid for it fortunately).
Had another car gets its catalytic converters sawed off. It was my station car, an old odyssey van, and it just wasn’t worth replacing the exhaust system as much as I loved that car (had like 245 k on it).
