250/280 SL (1966-71), English language
280 SL (1968-71), German language only :evil:
Each one for only about $30 including VAT. Send an email to classic.literatur@daimlerchrysler.com
Also the Technical Data Books are still available:
for Pagoda's from 1963-oct 1966 in English or German, from nov 1966-1971 unfortunately only in German. Cost: about $39.
The shop manual (Big Blue Book) is available for Euro 89, however only in German. Also parts books in print or on CD. The Classic Center in the US sells a CD rom with owner's manual, parts book AND shop manual, all on CD so you may want to get this if you're limited to English.
