2005 S4 cab tiptronic under 8k miles at dealer... items to check for?

Hello. I am acquiring a very low mileage (under 8,000 , really) , super condition S4 cabriolet, 2005 from an Audi dealer.

My local Porsche shop has a dedicated Audi mechanic who told me a 2005 of this car from a dealer should be a great acquisition. I am coming from a Jaguar XKR coupe 2002, and previously a 2000 Boxster (5 years), so I am no stranger to maintenance and knowing a mechanic well.

Items that I should still check for?

Do I need to have the car checked by a different place than the dealer selling it?
