Description
Here I have for sale is my incredibly rare and exceptional condition Audi C4 S6 Avant 20v 5-cylinder Turbo 6 Speed Manual.
This is a low mileage example sitting currently on 127, 500 miles.
There are only a handful of these left on the UK roads and even less in this condition and spec.
This particular model is the run out ‘Plus Spec’ gaining additional extras such as digital climate control, electric tilt/ slide steel sunroof, piano black window accents, retractable rear window blind, carbon accents with blue fleck, BOSE 6-disc systems with factory subwoofer etc. the list goes on. Most importantly though, this car is spec’d with the optional and stunning Nogaro Blue Alcantara/ black leather seats. These are electrically operated and contrasts beautifully with the Avus Silver exterior paint colour. Car also comes spec’d with a stowable, integrated inflatable load through ski-bag, should you decide to take this beautiful machine on a round trip to the Alps…

• Air conditioning radiator

Estimated cost of the above work is in excess of £12, 000 and has unlocked the true potential of this car improving from standard. Car pulls extremely well, handles much better due to upgraded suspension with zero loss to ride comfort. Sixth gear pull on the motorway is exhilarating. Classic old school turbo delivery that has put a smile on my face every drive.
This car has had some minor cosmetic upgrades which all original parts remain available. This includes the original wheels that the car was spec’d with from factory. These are the ‘Plus spec’ wheels that are rarer than hen’s teeth (see last picture). All badges removed for a cleaner look will be provided with the car and can be put back on at ease should the new keeper prefer, along with original OEM gear shifter etc. Car can also be provided with some rare performance upgrade parts like a rally spec large diameter front intercooler for example should the new owner look to upgrade for more power. These upgrades alone cost thousands.
Private plate A22 TBO will be included in the sale of the vehicle. This is a nod to the legendary Audi 2. 2 Turbo engine that makes this vehicle stand out from the rest. With prices of the UR Quattro now quite stratospheric, this car - mechanically an estate-bodied UR - represents great value and I am sure will prove to be an investment for the next owner. History available with this car is nothing short of amazing. Every receipt has been kept by myself and previous owners from the day it left the factory from Germany. I have invoices of work going back into the 1990's. Every paper MOT has been kept that details what work has been done. Tens of thousands of pounds of servicing invoices are evident that has kept this car in the phenomenal mechanical condition. Cambelt and water pump replaced 2023 with only 7000 miles since.
Along with the comprehensive list of history available with the car comes with:
• Original wallet including service history, owner manual, dealer directory, customer information etc
• Rare period brochures and accessory catalogues
• Old MOT and tax discs
• Every invoice from last few years including upgrade expenditure
• Unbelievably, 3 factory keys are still present with the car
• Original chip
I am sure I have missed a load of important things but there is just so much to talk about!
The overall condition of this car can be described only as exceptional. Exterior paint work is fantastic and the interior has been respected and cared for by all owners. Being picky, the only notable points of the car are:
• Couple stone chips on bonnet
• Light scratch on front bumper
• Passenger wing mirror cracked
• Rear light has a crack but barely noticeable
• Sunroof sticks in one corner and needs attention
• A bulb in the dash is innop – can be read in daylight no problem. A new LCD panel is included in with sale. Haven’t sorted as hasn’t caused me any problems
As always with any of my vehicles, I have tried to be as transparent as possible and highlighted any issues. For a 30-year-old car, all of the above can be forgiven and can be considered as relatively simple to repair.
Genuine reason for sale. I now have too many vehicles and cannot drive them all. Unfortunately, this beautiful S6 Avant isn’t getting driven as much as it should be and belongs to someone who is going to enjoy and drive it as much as possible.
MOT is valid until June 2026 and has no advisories.
Price is £15, 995 ONO
