Looking at a 14 plate S60, few Q's

[montecarlos]

Hi sorry for any ignorance involved here, I've got very little knowledge of Volvo's I'm doing my best to find this stuff out myself but you know how it is... Conflicting info all over the place.

So the car in question is a S60 D4 SE spec, priced at around £9000, 14 plate with a 64,000 miles.

My questions are as follows.

Apparently autotrader states the acceleration as 6.9s 0-60 which is somehow faster than the D5? I'm assuming this is listed wrong. I'm not hugely concerned, my main requirement is that the car is strong enough in power to easily over take on single lane A and B roads. It also states £0 road tax and a claimed MPG (combined) of 74mpg. The 74mpg seems extremely ambitious, but I'm hoping for about 55mpg average on a 33 mile run at 60mph? Is that doable?

My other question is regarding heated windscreen.

The car I am looking at has the winter pack including heated front seats. Does this winter pack include a heated front windscreen and if not, is there an easy way to know if a particular car has one from the button layout in the centre console? This is something I would like to have but it's not crucial.

Lastly, sound etc. Are the base level speakers any good and can I use my phone via bluetooth (perhaps dock it and use android auto on the phone) to play music? Or is there a good aftermarket option to add android auto function to the car?

Any other advice on what to look for? Don't mind spending a few quid once I get it.

Thanks
