Two-time Gull Wing Group International show winner since 2017 - Low
original miles - Odometer reads 41,000 - One of the finest and most
iconic postwar sports cars ever produced Universally recognized as
a design and engineering tour de force, the 1954-57 Mercedes-Benz
300SL "Gullwing" Coupe stands today as one of the ultimate sports
cars ever produced. Upon introduction, the road going 300SL carried
a virtually unbeatable reputation, having been derived from the
devastatingly successful 'W194' competition coupes which returned
Mercedes-Benz to racing and utterly dominated the 1952
international racing calendar. Its 1954 New York debut rewrote
history as the first time a Mercedes-Benz model was introduced
outside of Germany. According to early-1950s factory records, its
"SL" designation translated to English as "SuperLightweight" and
its many race-derived features included an extremely light, yet
strong tubular spaceframe and fully independent suspension.
Powering the 300SL was an SOHC 3.0-liter (2,996 cc) straight-six
engine with competition-typedry-sump lubrication. Its Bosch
mechanical fuel injection system was a production-car first. Power,
rated at 240 bhp at 6,100 rpm under American SAE testing and 215
bhp at 5,800 rpm under the stricter German DIN rating system, was
delivered through a 4-speed manual gearbox. Offered with a standard
3.64:1 final-drive ratio, the 300SL could be equipped with several
other factory-available ring-and-pinion combinations, making the
300SL potentially the fastest series-production car of its time,
with magazine road tests reporting top speeds of 130 mph and
beyond. Production of the semi-hand-built 300SL "Gullwing" Coupe
continued into 1957, with 1,400 built in total. Considering all the
greatest postwar sports cars, the Mercedes-Benz 300SL "Gullwing"
continues to top most every "Greatest Cars" list compiled and
published today. This beautifully restored and maintained example
from 1955 is a confirmed matching numbers example (chassis, body
and engine) with truly wonderful single-family provenance for the
past 65 years. Delivered new to Mercedes-Benz New York on September
1, 1955, this 300SL "Gullwing" was finished in Code DB534
Feuerwehrrot (Fire Brigade Red) paint and Code 953 Black leather
upholstery - the combination it sports today. It is now offered
from single-family ownership and care since it entered the life of
Tony (Anthony L.) Dunne, a 22-year-old MIT-educated engineer from
Troy, New York, in April 1961. According to an account from the
Dunne family, Tony was thrilled to see an ad published in The
Philadelphia Inquirer for this car, and when he called in response,
the salesman said he'd already received an inquiry, so the first
person to show up with money in hand would get the car. Tony went
to work the next morning and advised his boss, "I have to run an
errand; I'll be back as soon as I can" - which was not a lie,
although he did not, in fact, make it back to work until the next
day. Having received a loan from his father, a judge in Troy, for
$4,500, Tony raced to the dealer, was first to arrive with the
funds, and purchased the car, which has remained with the Dunne
family ever since. One and a half years later, Tony took his bride,
Helene, on their honeymoon to Nova Scotia with the red Gullwing. On
their way, Helene noticed a line of cars following them and asked
Tony to pull over at the next town so they could pass. He did, and
much to her chagrin, so did everyone else - so he put Helene out on
the curb and gave rides to everyone who wanted one in the
futuristic Gullwing. Not long after their honeymoon trip, the
Gullwing ended up in the one-car garage at the Dunne family home in
Quaker Hill, Connecticut, replaced by station wagons but
occasionally getting some love from the kids, who would climb in
and play Speed Racer. Dubbed "The Mistress" by Helene, the 300SL
spent much of the following decades mostly unused until the late
1980s, when Tony sent it for a complete restoration by Paul Russell
& Company in Essex, Massachusetts, where it shared space with famed
designer Ralph Lauren's own Gullwing. Following completion of the
restoration in 1992, the beloved Gullwing was driven in several
Gull Wing Group events, with venues including Montvale, New Jersey,
the Greenbrier in West Virginia, Chateau Frontenac in Quebec City;
and to St. Louis, where it was photographed and featured on the
cover of the Gull Wing Group newsletter, The 300 Star Letter, under
the famous Gateway Arch, and on tours around New England before
eventually making its way to Saratoga, New York. A repaint was
performed in 2015. Beginning in 2017, at about 27,000 miles, "The
Mistress" was sent to Albrecht Stachel and Alison Fisk of Brooklyn
Motoren Werke in Brooklyn, Wisconsin, where it received mechanical
upgrades allowing it to thrive with today's oils and gasolines,
plus the addition of an electric cooling fan and steel braided
fluid hoses. Most exciting for his children, Tony finally let them
actually drive the car! On two occasions since 2017, this 300SL has
won awards in Gull Wing Group show competition, confirming its
excellence and the loving care it has received with the Dunne
Family. In 2022, the 300SL was inspected at the Gull Wing Group
Convention, and its FIVA Identity Card (no. 107FRN118), was duly
issued on November 15, 2022, and accompanies the sale of the
vehicle. Tony passed away in 2024, and his family has now
reluctantly decided to allow "The Mistress" to capture the heart of
an enthusiastic new owner, who will have the fabulous and truly
rare opportunity to add to her life story. Original mileage is low,
with the odometer reading 41,000 at the time of writing.
Accompanying documents include the aforementioned FIVA Identity
Card, restoration and maintenance records, the original
factory-issued Data Card production record and a written account of
this Gullwing's 65-year love affair with Tony Dunne and his entire
family. -- This item is a part of Saratoga Motorcar Auction's
