Well, he’s at it again; the same seller as the 1984 Audi 4000S quattro in Laguna Seca Blue and earlier 1990 Coupe Quattro in Ginster Yellow is now selling his 1983 Quattro. These cars have been pretty rapidly appreciating, pulled upwards by the popularity of the E30 M3 and resurgence of Audi’s campaign to recognize that it made cars before the A4. Undoubtedly, this Quattro is much more valuable than the last two offerings from this seller – but is it the one to buy? The last few examples that we’ve seen have had some rare but polarizing modifications that arguably hurt more than helped the value of the cars for sale – is this legend the same?
