The black one with red leather looks like the one to go for, as it has a double DIN dash, ready for a straight RNS-E swap!
Only things that concern me though are the colour and the front grille: Phantom black was never an option for the A2, unless the original owner specced a £1500 custom colour! and the smooth grille would have to be a retrofit, as 90s always came with the slatted grille.
Smith Knight Fay is my local dealer, so if you want me to take a look just ask.
Cheers,
Mike
