Find of the Day: 2004 Nogaro Blue Audi S4 Avant 6-speed

words: Bill, photos: Dr_EuroCar via Cars&Bids

Funny how I mentioned the other day how I wished our Find of the Day was a B6 Nogaro Blue S4 Avant with a manual transmission and then boom, this shows up.

This is a B6 Nogaro Blue S4 Avant with a manual transmission…pretty much the perfect Avant for me and it has a little surprise; a new engine. Here’s the ad:

Doug’s Take

The B6 S4 Avant is one of my favorite Audi models, as it combines wagon practicality with a potent V8 and Quattro all-wheel drive. This particular S4 is even cooler, though – not only because it boasts a 6-speed manual transmission, but also because of its VERY desirable Nogaro Blue exterior AND interior combination. It also touts a long list of desirable modifications, including a tune, upgraded suspension, and those cool 19-inch Bentley wheels. The seller has also provided an extensive photo gallery showing this S4 Avant from all angles, which always increases the appeal.


THIS… is a 2004 Audi S4 Avant, finished in Nogaro Blue with a Black/Nogaro Blue interior.

  • This S4 is equipped with a 6-speed manual transmission.
  • The attached Carfax history report shows no mileage discrepancies in this S4’s past. It also confirms that it’s been registered mostly in California and Washington from new.
  • The seller reports that this S4 received a brand new replacement 4.2-liter V8 at 139,000 miles in April 2017. Photos from the engine installation can be found in the photo gallery.
  • Factory equipment includes Nappa leather upholstery with Alcantara inserts, power-adjustable heated Recaro bucket seats, a navigation system, dual-zone automatic climate control, and more as listed below.
  • Modifications to this S4 are extensive, and the full list is detailed below. In addition to the replacement engine, highlights include a JH Motorsports tune, BC Racing coilover suspension, 19-inch Bentley wheels, B7 RS4 interior components, and more as detailed below.
  • Introduced in 2000, the second-generation A4 was built on Volkswagen Group’s “B6” platform, and it was initially offered only as a sedan. Audi released the Avant (wagon) body style in 2001, and it launched the high-performance S4 for 2003. Offered as a sedan and as a wagon, the S4 came equipped with Quattro all-wheel-drive and an all-aluminum V8.
  • Power comes from a 4.2-liter V8, rated at 340 horsepower and 302 lb-ft of torque in stock form. Due to the modifications performed to this S4, it likely produces more power, but a dyno sheet was not provided to confirm. Output is directed to all four wheels through a 6-speed manual transmission and Audi’s Quattro permanent all-wheel-drive system.

  • 18-inch “Avus” alloy wheels

Ownership History

The seller purchased this S4 in February 2017 and has added approximately 33,500 miles since.

While the chassis may have 172,500 miles on it, as mentioned before and in the ad, the V8 was replaced with a brand new one roughly 35,000 miles ago so you can pretty much stop asking if the chains were done. This combination of color, engine, interior plus 6-speed manual is the perfect storm for me. Alas, i already have 5 cars in the driveway plus 2 kids in college so I can say with confidence (though sobbing the whole time) that I will not be bidding on this Blue Heaven. Speaking of bidding, as of this writing, there are 19 bids and it is up to $23,000. There are two days left so within the week, you could have this perfect storm in your garage.
