I owned a w210 from new. Among the most troublesome cars I've ever owned. HVAC reliably blew cold from November through March, hot from April through October. Replaced lots of electronic stuff, mechanicals, and it rusted like an old tin can. Fortunately, I took the extended warranty from, so the dealer gave it lots of love. It did look great, high above the traffic on a flatbed. It's a generation that you should skip.
