Recommended Posts


1999 Pre-Facelift Audi S4 Avant 'Stage 3' K04


Ming blue with Silk leather, black carpets and head liner and Aluminium trim.

Bose stereo

Factory HID's



Current mileage is 158180 miles and growing steadily through occasional use. This is now a third car.

Oil service 16 Aug 13

Fresh MOT until 15 August 2014. The car flew though yesterday with no advisories.

Tax expires 28 Feb 14.



I bought the car in Nov 2012 with 155,850 miles on the clock. This was the 5th car I looked at. The car came with a large amount of service history and all engine and chassis modifications completed by the previous owner – a motorsport mechanic – between Aug 11 and Aug 12 (148 and 155K miles). K04 Turbos and other engine mods completed around 152K and was built to be the ultimate fast road spec. IRO £9000 was spent on the car in parts alone to refresh and upgrade it. It comes with two original keys and a smart Audi S4 keyring. This is a very good example of a well-modified S4. It is bone-dry underneath, no leaks or issues mechanically at all.



Genuine RS4 K04 turbos completely reconditioned with 360 thrust bearings by Turbo Technics. Paperwork for the turbos included.

Service History:

Absolutely masses of service history with a fully stamped service book plus all receipts dating back to 2004. Also a pile of MOTs and tax discs dating to the same period.


Latest work:

MOT and oil change at 158171 miles with very expensive Castrol Edge 5w40.


Bad points:

One very minor pin dent to OSF wing and a small patch of lacquer peel on NS of front bumper.

1 of the cup holders in the cabin does not work

Horns connected and working but require a bracket to mount them in the engine bay, having had to relocate them when oil cooler was fitted.



This is an outstanding car that I spent several months searching for (and travelled 200 miles to collect). I have loved every minute of the last 9 months of ownership. I had no plans to sell it. However, my new job requires a 60-mile daily round trip commute and this is simply not the car for it. I hope it goes to a good home and to someone who will look after it.


Private plate not included.
