This 1984 Audi Quattro is the recent subject of a lavish build intended to disguise heavily upgraded performance within an immaculately prepared stock shell. Equipped with a built 20V motor, six-speed transmission, and impressively specced brake and suspension components, it sounds like a real wolf in sheep’s box flares. The car was advertised for a while on Kijiji with no price stated, but the seller has now offered it here on eBay in Ontario, Canada with a $30,000 Buy-it-Now.

Beginning with a bare chassis that was treated to a reportedly $10,000 respray in 1997, the car then sat unfinished until 2009 when the seller embarked on a seriously ambitious build, further detailed here on an externally linked thread. The auction details a litany of parts and procedures thrown at the car, for which the seller claims he has in excess of $25,000 in receipts for.

Using stock pistons and compression, but with nearlyeverything else upgraded, the far forward-flung five puts out a four wheel dyno-charted 336 HP, equating to roughly 420 at the crank. In the seller’s own words: “needlessto say, it is fast.” There’s a link to a short YouTube video of said dyno run, and no surprise, it sounds fantastic. The chassis’ claimed overall mileage is 136,000, but seeing as the seller claims it’s undergone less than 13,000 km since completion, this number may actually reflect klicks and not miles-either way, it’s a moot point seeing as it was a ground-up build.

Not much detail is given on the car’s overall cosmetic condition, but from the looks of things it’s super-clean, with only lightly patina’d seat covers belying its true age. Said to be one of only 17 Ur-Quattros imported into Canada for 1984, it’s a non-sunroof car which is a plus for weight savings and chassis rigidity, if not summer night cruises. We absolutely love the builder’s decision to retain 100% stock appearance, even down to the original Ronal wheels. Euro bumpers are the only exception to that statement, but these are a clear improvement, anyway.

Though far from inexpensive, it’d likely be impossible to replicate for anything near what is being asked. One of the only downsides to this car we can think of is that we’d be afraid to drive it hard through snow, muck, and dirt-the kinds of surfaces it was made for, and the keys to unlocking your inner Stig Blomqvist . Slow in, fast out just doesn’t jive with the Ur-Quattro’s style, so perhaps it’d be best to get out there and earn a few battle scars before you’d lose the nerve, then drive it sideways in the nastiest of conditions every chance you got.
