Hi, newbie member here… I can comment slightly, I don’t have the d5 version that your looking at but I do have the Audi a8 lwb 3.0v6 diesel 2017 model just before the facelift…
I have owned the car since 01/10/2021. I purchased the car with 19,306 miles and I am currently sitting at 246,000 ish.
i have to say, I’ve had a few lwb cars, this for me is the best car to date , I’ve owned Mercedes s class, bmw 7 series and my last car was a Jaguar xjl… for me, the Audi a8 has been the best, by far may I add…
I love the driving position, the seats, the super smooth gearbox, the suspension, customers absolutely love the car, it’s been absolutely perfect.
i have the car serviced every 6 weeks, and other than tyres and brakes along with the servicing it’s been faultless.
after 5,600 hours of driving my long term memory states 43.1 mpg which is pretty good for such a big car.
im hoping to get the car to around 350,000 before moving over to the d5….
I’ve heard of some issues relating to air suspension after a certain mileage and also adblue issues with the pipe, however, I’ve encountered none of these, maybe I got lucky.
the jag was certainly a winner In the looks department, but basic inside and a bit ghosty with electric issues.
the bmw was a nice but feel rear seat passengers suffered a harsh ride, maybe because my was an m tech version possibly.
the Mercedes was nice as well, however main dealer pricing and customer service meant I wouldn’t buy another one..
for me, Audi will remain top spot.. it ticks all boxes, I quite like the fact that it floats under the radar in my profession… if the lottery numbers come up then I’ll head to rolls Royce, until then, the A8L is just perfect.
Hope that helps.
