2018 Lexus LS 500 — Should You Buy One?

Typical asking price: $45,000–$62,000. This is one of the more reliable vehicles in its class — here's what to watch for anyway.

Kestrel Take

The reliable flagship — the LS 500 delivers genuine flagship luxury, a stunning cabin, and a twin-turbo V6, with the crucial Lexus advantage: it's far more dependable and cheaper to own than the German flagships. If you want a big luxury sedan without the flagship repair-bill anxiety, this is the one. A documented LS 500 with full history is arguably the smartest used flagship buy; verify service and the (many) tech features, and enjoy the peace of mind.
