The seller describes this ’73 e9 BMW as “Unbelievable”. The pictures don’t lie, it’s the “Needs a paint job” claim that makes us wary. It does, indeed need a paint-job, in addition to several thousand dollars worth of body work. e9 BMWs (2800s, 3.0CSs and CSLs) are Teutonic Sirens: gorgeous to look at, relatively simple mechanics, but apparently not designed to persist in an oxygen-rich environment without rusting to smithereens. The currently hilariously low (no reserve) price only adds to the siren-ness… That said, the low purchase price, generally dubious condition, and pre-smog title leave the door open for a slew of upgrades. We’d take it down to metal and only add back what we really needed; things like a fuel-injected stroker M30, 5 speed transmission and a good set of Recaros. And just for kicks we’d patch the rust but never repaint it. For those with their tetanus shots up to date, it’s on eBay motors at $1625 with no reserve.
