New January 2009, current mileage 40,000. Water ingress issues meant factory have had the car to correct so allowing for that and holidays away from car would say probaly mileage accumulated over 14 months of driving.
Apart from scheduled servicing every 10,000 plus an extra fluids change every 5,000 the car is on it's second set of tyres, has had new brake discs at the front at 35,000 miles, new donut on driveshaft (warranty) at 30,000 miles, replacement speedometer due to faulty electronics in the speedo (fault developed when leaving factory on Jan 2nd 09), drivers door acctuator under warranty.
So, on the whole, mechanically pretty excellent. Yes, there seems to be an electronics issue for many which I guess will eventually get resolved but on the everyday mechanical stuff not much to be concerned with.
The drivers seat does get scuffed and I have a simple solution which means that it doesn't get any worse and the design of the roof when folded does have a wear point which I can see will eventually put a hole in the fabric. Working on a solution to prevent that.
I expect that there are a bunch of Aero's on higher mileage but unlikely to be many S4's at this level. If we discount the issues we all know about, water finding it's way in and the potential leather wear and tear due to small doors and tight spaces getting in and out of the car, I think that overall the reliability is fine. Just need to resolve the electrical glitches for people.
Both the factory and Richard Thorne Classic Cars do a fantastic job with the car and between them go out of their way to ensure things are right.
