Beneath its streamlined styling, the Type 964 generation Porsche 911 that debuted in 1989 boasted considerable functional and comfort upgrades. Power steering, coil springs in place of torsion bars, and anti-lock brakes did not so much tame the 911 as they did allow Porsche engineers to explore higher limits.

In March of 1990, the 911 Turbo was revived. Under its huge fixed rear spoiler, it used a 3.3-liter flat six derived from the 930 Turbo engine. Revisions reduced its legendary turbo lag, making its 315 hp more accessible. The 964 Turbo was a force to be reckoned with.

It did not use the all-wheel drive of the Carrera 4, but its wider rear track that accommodated 255/40-17 tires gave it improved handling tenacity. The 964 Turbo’s beefy haunches gave it a road presence unlike any other 911 before.

Painted in rare paint-to-sample Meteor Gray over special Matador Red special leather upholstery, the 1991 Turbo offered here was special-ordered by an exceptionally discerning original owner. Its build sheet and original window sticker show a staggering $20,621 in optional extras that pushed its original list price to $118,421. It is unlikely that any other 911 Turbo was ordered the same way, making it a true one of a kind. The car’s original owner, an attorney in the Washington, D.C., area, was so enthusiastic about his 911 Turbo that he visited the Porsche factory in Germany to watch his car be completed. A photo of the original owner with Ferry Porsche from that visit will be included with the file.

Functional options included a limited-slip rear differential and a rear window washer. It is not until the 911 Turbo’s door is opened that its full leather interior—extending to its door opening levers, control knobs, seat belt housings, and Turbo S center console—comes into view. Additionally, the 911 Turbo benefits from factory-installed rosewood trim on its dashboard. Its extra-cost sports seats feature partial power adjustment and heating. Like the rest of the 911 Turbo, the interior shows no signs of use and presents in nearly as-new condition.

The 911 Turbo was delivered to its discerning first owner on 30 July 1991, to the Porsche dealership in Arlington, Virginia. Subsequent servicing was handled by Dulles International Motorsports, Limited, through 1999, and then by Hollin Hall Automotive in Alexandria, Virginia, through 2015.

The 911 Turbo wears Porsche-approved Michelin Pilot Sport tires around its Cup wheels with painted center caps that were installed a few hundred miles ago in 2015 by Porsche of Monterey. Auto Strasse in Costa Mesa, California, recharged its air conditioning in September 2016.

This exceptionally preserved, meticulously optioned 911 Turbo will be delivered to its new owner with its original tools, books and manuals, and service records.
