2014 Mercedes-Benz C250 — Should You Buy One?
Typical asking price: $11,000–$16,000. This is one of the more reliable vehicles in its class — here's what to watch for anyway.
Kestrel Take
A classy, comfortable compact luxury sedan with the efficient 1.8L turbo four (C250). It feels special and is cheaper to buy than a fresh one — but it's a used Mercedes, so budget accordingly: oil leaks, cooling, and electronics are all real. Only buy one with service records and a repair fund; a bargain-priced neglected C-Class is a trap.
