This 1984 Audi Quattro comes equipped with a rare and very interesting Treser conversion, fitted from new and reportedly responsible for adding 8k GBP to an already hefty ~18k MSRP–making for a total of around $115,000 in 2017 dollars. As head of Special Vehicle Development from 1976 and later Quattro development from 1980, Walter Treser knew these cars inside out, and thus decided to leave Audi in 1982 to start his tuning firm. This car received virtually the whole Treser catalog, including extensive modifications that raised output from 200 to 250 HP–both interior and exterior styling as well as suspension have also seen changes. Condition looks excellent throughout, and mileage is given as just 36k. Find it here at Classic Hereoes in Uckfield, East Sussex, England for 43k GBP (~$54k USD today). Special thanks to BaT reader Kyle K. for this submission.

This paint color is called Montego Black Metallic, and it still looks to hold a very nice shine. The wheels and wing are Treser items, both of which have a totally appropriate and very 80’s aesthetic. The car itself sounds to have been very well cared for over the years, the ad noting four private owners, the last two of which purchased it from the very same dealer now offering it to a fifth.

Inside, distinct and rather cool looking seats are optional Treser items, though everything else looks to remain standard–a Treser steering wheel would be expected as well, though we’re not disappointed to see it’s been omitted as it wasn’t a very attractive design. We actually like a nice brown interior (in old German cars, anyway), and this one looks to be just as well preserved as the exterior.

Quoting from the ad: “This particular car is a 1984 WR engine version. That’s the 2144 CC, 10-valve, single overhead camshaft engine producing 200 BHP. Converted to Treser spec from new by the UK Treser agent Central Garage in Cobham. The hand-built Treser engine featured larger inlet and exhaust valves, reworked and polished cylinder head and ports, Treser camshaft, Treser air box, reworked fuel injection, and a larger intercooler taking performance to 250 BHP. This particular example also benefited from the Treser wheels, rear spoiler, suspension conversion and seats.”

Treser went on to build some pretty wild cars before closing in 1988, the strangest and most striking of which was this bizarre folding hardtop UrQuattro Roadster.
