Spotting Premium Audio / General Buying Advice

[pchmax]

Hi All,
I'm heading off to see a Vantage on Saturday, 2007 with good spec. The advert states premium audio but how do I check for sure? I've only looked at cars with standard audio so grateful for info.

Also if anybody has any other tips would be grateful to receive any advice.

Many thanks

Re the Premium audio, turn it on and it states 'Premium Audio' in the display on the initial boot-up.
