Offered for sale is a gorgeous, ell-cared-for, ery original, umbers matching, eavily documented 1970 Mercedes-Benz 300SEL 6.3 finished in desirable and attractive Dark Green (DB 291) over Cognac leather. The 300SEL 6.3 started out as an auspicious personal project by company engineer and amateur racer Erich Waxenberger, ho was able to somehow squeeze the heralded 6.3L V8 M100 engine from the flagship 600 limousine into the popular Paul Bracq designed W109 body, hich until that point was offered only with a 6-cylinder engine. Seeing the opportunity to more comprehensively utilize the M100s production facilities, ercedes surprisingly decided to slate the car for production, eveloping Waxenberger’s weekend project into the ultimate wolf in sheep’s clothing – an elegant and supremely comfortable sedan that provided performance similar to – if not better than – most of the dedicated sports cars of the era. Independent road tests confirmed an astonishing 0-62mph time of 6.3 seconds (fittingly) and standing quarter mile time of 14.2 seconds.
