2018 Acura RDX — Should You Buy One?
Typical asking price: $20,000–$28,000. This is one of the more reliable vehicles in its class — here's what to watch for anyway.
Kestrel Take
A reliable, value-focused compact luxury SUV — the RDX pairs Honda mechanical dependability with a comfortable, well-equipped cabin and the durable 3.5L V6 (naturally aspirated, no turbo, timing belt). It avoids the German repair bills entirely. A documented RDX is one of the most sensible used compact luxury SUVs; verify the timing belt was done (or budget for it), check the electronics, and enjoy years of low-drama, dependable ownership.
