The Focus is Ford's compact that splits into two completely different ownership experiences depending on what's bolted to the engine. The 2012-2018 PowerShift dual-clutch automatic fails so reliably that owners budget for multiple $2,000 transmission replacements, and the 1.0L EcoBoost's wet timing belt sits in hot oil degrading toward catastrophic engine failure every 60-80k miles. Manual transmission models across all generations are a different story, scrappy, fun to drive, and genuinely durable, with the 2000-2011 cars earning particular loyalty for hitting 200k+ miles on basic maintenance. Buy a manual from any era and you'll likely be fine; buy a 2012-2018 automatic and you're inheriting someone else's repair bills.
The Mazda3 is what happens when a compact car decides it's too good for its price bracket, and the interior actually backs it up. The 2.5L engine is bulletproof (owners routinely see 200k+ miles), but the 2019 redesign swapped the old multilink rear suspension for a cost-cutting torsion beam that blunts the handling sharpness earlier models were loved for. If you want a refined daily driver that feels expensive and runs forever, this works; if you want the sporty Mazda everyone raves about, hunt down a 2014, 2018 instead.
