📚 Vehicle History

Brand Heritage:

Aston Martin has a long-standing reputation for building luxurious, high-performance sports cars with a rich racing heritage.

Model Evolution:

The DB7 was a pivotal model for Aston Martin, revitalizing the brand. It evolved from the DB4, DB5, DB6 lineage, offering a more modern platform and engine while retaining classic Aston Martin styling cues.

Engine Introduction:

The DB7 initially featured a 3.4L inline-six (supercharged), but the 1998 model year is primarily associated with the V8 engine introduced later in its lifecycle (or continuing from the previous year's V8 Vantage variant if applicable to the 1998 spec). The provided manual content clearly indicates V8 engine coverage.

Production Period:

1994-2004 (DB7 platform)

Manufacturing Location:

Newport Pagnell, Buckinghamshire, England

🏆 Awards & Recognition

Recognitions:

While specific awards for the 1998 model year might not be widely publicized, the DB7 was critically acclaimed for its design and performance upon its introduction, revitalizing the Aston Martin brand and earning it a place among automotive icons.
