The 4K's never had a digital dash...The 87 Audi coupe was the only Audi to have an entirely digital dash...As for reliabliity...Try to find one in a junk yard...Out of ten cars I've located around the country, none had the display that wasn't sold yet....A new display costs 1000+ dollars from Audi and you have to wait for Hans in Germany to dust one off.....
