2016 Mercedes-Benz C300 (W205) — Should You Buy One?
Typical asking price: $14,000–$21,000. There are 2 high-severity known issues you need to know before handing over a check.
Kestrel Take
The interior alone justifies the badge — this generation genuinely felt like a smaller S-Class. The M274 turbo four is reasonable, and the real costs are electronics, air suspension on equipped cars, and the fact that every part says Mercedes on the box.
What we checked
No public record to reconcile against
We don't yet have a public record to check this one against. Federal complaint records thin out badly on older vehicles, so there is little to check against. What follows is our own write-up, and it has not been reconciled against an official record. Treat it as a starting point, not a verdict.
