I've been scouring the internet looking at probably buying a face lift, I've found a 1999 and got a friend to get me the VIN from the reg number from the ad so I could pull up the datacard.......It has ADS, is this a good thing or a bad?...Something to steer clear off or be happy about?...Obviously it's going to be more complicated and expensive to fix, but are there any known reliability issues with that suspension?...Cheers. I forgot, it says ADS with skyhook...I'm fkd if I know what that means.
