Would you buy this car?

I used to own a 2004 S500 4Matic before buying my Buick LaCrosse. I was browsing and happened to find a 2011 S500 4Matic with 45,000 miles for $35,000. I'm not trying to be cheap, it just caught my eye. It has all the standard features. It has Parktronic but I didn't see Distronic listed which is something I had before. Would you think about buying a car with these miles for that price? I would lose Pandora integration which I really like but I'd still have Bluetooth. I did have quite a few repairs on my 2004. I did at least one Airmatic repair out of pocket on my 2004. Has Airmatic gotten any more reliable?
