Advice on doing a deal with a Skoda dealer

I am looking for a TDI DSG Superb estate and have been offered one through a Skoda dealer, which will apparently be coming into stock soon.  It is on a '10" plate (Superb Mk2?) 170bhp TDI Elegance estate with DSG and 50,000 miles.  

The car will apparently be sold with 2 years servicing and warranty and will on for about £12,300.  I anticipate that I will make the purchase using the Skoda PCP scheme, as they are initially offering £500 towards the deposit to which I plan to add another £2500 - £3000.

Is there anything I should be looking for at that mileage?

Critically, what sort of things should I be looking to get done as part of the deal?  i.e. DSG oil and filter change.

Any tips on striking a deal when purchasing using their PCP scheme?

Is the 2nd hand Skoda warranty alright?
