You're shopping two completely different cars under one badge. The '58-'67 classics are wide, low, chrome-heavy icons that still command respect at every stoplight, owners restore them obsessively, parts flow freely, and the enthusiast worship is real. The modern front-drive versions (2000-2020) are roomy fleet sedans with a recurring transmission weakness, rental-grade interiors, and all the charisma of a municipal parking ticket. Police departments used them for detective work but found them wanting for patrol duty. If you're hunting a classic, you're buying American automotive royalty. If you're considering a used modern one, budget for a transmission rebuild and manage your expectations accordingly.
This asymmetric three-door splits into two personalities: buy the base 2.0L and you get a buzzy economy car that looks quick but drives like it's apologizing, while the Turbo and especially the N deliver genuine hot-hatch thrills that embarrass cars twice the price. The 2013s grenaded engines with rod knock and bearing failures, avoid completely. Later first-gen models (2015+) and the second-gen (2019-2021, now discontinued) are far more solid, but every year suffers from comically persistent horn failures that need replacement after replacement, even under warranty. If you're considering a 2015+ Turbo or any N, commit to 4,000-mile oil changes and accept the horn lottery, you'll get a legitimately fun driver's car for used Civic money. Skip the base model unless you need cheap transport and nothing more.
