The Dialynx car has the rear wing vent blank in "high" position ahead of the rear wheel - where the rally car has an actual vent, whereas the factory road car has a blank at the bottom of the wing - which clearly does nothing. I never understood why the rally car and road car have the vent / not vent in different positons

The vent on the rally car was put in part of the first extensions to the homologation, one of many items from page 25 onwards in this:

Speaking to the owner of a very nice example of a converted car he said that it took 2 years to source all the correct parts including the doors, the windscreen rake isn’t a deal breaker for me, I think it shows more on a road going version in a solid colour opposed to a car with a rally livery, as there’s more to distract the eye on the rally car.
From what I’ve read, for UK cars, there were around 20 Dialynx cars and 3 Keith Edward’s cars, using Dialynx parts, then you have all the other cars that are converted in various parts of the world.

I like these guys but the costs are what you’d expect…

Pretty much inherent in the Quattro system, where the front diff sits ahead behind the clutch. A bit bonkers to be honest.

Others, like the Sierra XR4x4 and Cosworth had a conventional lay shaft and diff, with one halfshaft going through the sump, a couple of feet or so further forward. Or, if you prefer, the engine is a couple of feet further back. Helped if you only have 4 or 6(3) cylinders in a row, not 5.

The red one above has gone but if you need an Xmas present to yourself, this has gone up for €700k! Lovely colour and trim combo. Factory sports exhaust with the single tip according to the ad.

They are only going one way in terms of prices, and more so than any of the other road going Grp.B cars (with possible exception of the S4) largely because they were by far the best in terms of actually being a good road car.
That blue one reminds me of my only quattro experience. My Renault 5 Turbo 2 was at a specialist in North London, having some work done. It needed a few parts including the Bosch K-Jetronic fuel pump, as fitted to the Golf GTi. Anyway, the mechanic took me in a customer’s blue 10 valve quattro to the motor factors over at the then under construction new Wembley stadium, so it must have been about 2005/6. The journey was primarily along the A406 North Circular road. The driver nailed it, then slammed on the brakes for the first speed camera, then nailed it again and slammed on the brakes for the second speed camera and so on, all the way there and all the way back. I actually felt quite nauseous, but I doubt anyone could have driven that section of road quicker, without getting caught!

[grumpy]I'm sure the owner would have been chuffed to bits if he'd known that his car was being driven like that, especially given they ideally need about twenty miles to properly warm up.

If I had been taken for a ride in a customers car like that, I would have never of taken my own car back there again...!

It was said at the time, that all Ur-Quattros were driven flat out around the track around the outside of the plant as part of the QA shakedown. As with most folklore, who can say if it was true. Probably better for the engine than running at constant low revs for 1500 miles
Not sure about that story but seems likely. Porsche run the engine at full throttle for 90 seconds as part of the engine test process before being installed in the car. You can see that here:https://youtu.be/mOBl3tcGlLA?t=1931
I bought a new Boxster a few years ago. The running in procedure was simple - go easy for 500 miles until everything was bedded in, then after that, when everything's up to temp, drive it like you stole it. Up to the red line if you want - just don't hold constant revs for any length of time.

That's the crucial bit in bold. It takes ages for all the oil to come up to temperature in a Quattro. Or at least it does in mine. I guess maybe it's quicker in the earlier ones without the water-cooled turbo.https://youtu.be/mOBl3tcGlLA?t=1931

Another thing Audi allegedly did was squirt water at every Quattro for fifteen mins to make sure it wasn't leaky.
