1958→1959 Aston Martin DB4 Series I
In October of 1958, Aston Martin revealed their DB4 grand tourer to world. Unlike any other British tourers, it had a fastback body styled by Touring Superleggra of Milan, Italy. As such, the result was remarkably similar to the Maserati 3500.
The DB4 was a much needed replacement for the aging DB2 with its body-on-chassis design. The new DB4 used a pressed-steel chassis tub with a significant amount of round tubing to accommodate the aluminum body panels.
A new 3.7-litre straight six cylinder engine was designed by Tadek Marek for the DB4. It was fitted with SU HD8 carburetors for 240bhp at 5,500 rpm.
The first series of DB4s were produced in the period from October 1958 to January 1960. The Aston Martin Owner’s Club (AMOC) referred to these cars as Series I.
Some of the very first DB4s are easily identified by their lack of door window frames and lack of bumper over riders. After the first 50-or so cars, Aston Martin fitted frames to support the door-windows and combat whistling at high speeds.
After car DB4/249/L Aston Martin updated the model with a larger oil sump, disc brakes and a front mounted hood. This was determined as the turning point for the Series II cars by the AMOC.

Auction Sales History
Auction Source: ‘Rolling Sculpture’ 2015 NYC by Keno Brothers
Offered complete with a copy of its original build sheet, this DB4 from 1960, chassis DB4/245/L, is an original left-hand drive example that was sold new in the USA via West Coast distributor Charles Hornburg to Mr. Paul S. Pollack of Los Angeles, California. A rare and very desirable early ‘Series I’ car, it is highly collectible as one of about 150 originally built. This DB4 has particularly clean styling with its frameless doors, rear-hinged bonnet and the absence of the later bumper over-riders. In fact, it retains its matching-numbers engine, numbered 370/243.

‘3514 UG’ was acquired by the present owner in 2004 and subsequently treated to body and paint renovation (mostly around the front of the car); new headlining (being fitted at the time of cataloguing); and servicing carried out by the owner’s resident engineer, a former employee of marque specialists, Aston Engineering. One of the shortcomings of the Series I/Series II models is the lack of an overdrive; this car had one fitted by a previous owner in 2004 during a gearbox overhaul by Four Ashes Garage.
