I am looking to replace my 2001 Renault Clio and was looking at 3-4 year old Auris Hybrids.
My local Toyota dealer currently has a couple of Auris Hybrids that are within or near my price range:

- 2010 T-Sprit with Sat-nav, 4,500 miles above the average for the age, Silver, £8,999
(12 months warranty, the MOT & tax expired 3 months ago so I'm guessing it's been sitting on their forecourt for that time & the battery had gone flat when I had a look at it. Has 'first generation' sat-nav)
- 2012 T-Sprit with Sat-nav, 16,300 miles above the average for the age, 'Island blue' £9,999 (which is over my budget)
(2.5 years warranty, has small dent in one of the doors, updated sat-nav compared to above- Possibly "Touch & go", though not sure of advantages).

I drive around 8,000 miles a year so it would take about 2.5 years to bring the mileage down to average for the 2010 model, 8 years for the 2012 model (assuming I kept it for that long).

I really like the 'Island Blue' of the 2012 model, the 2010 is silver which is OK but wouldn't be among my first choices of colour.

I'm not in any desperate rush to buy so am tempted to see what cars get traded in this month with the new registrations (but this spec & price range in colours other than white isn't very common).

Here are my questions:

1) Out of the above two, which would be the better buy?
(Or would it be better to wait

2) £9,995 (for the 2012 model) is over my budget - How much could I realistically expect a main dealer to take off the price if I push them?

3) Would it be worth getting a 2nd years warranty for the 2010 model?
If so, would it be better to get this via Toyota or a 3rd party?

4) I wonder whether there might be any teething issues with the 2010 model that were resolved with the later models (I know the older model doesn't have a USB socket for the stereo but wonder if there were any other 'behind the scenes' improvements/tweaks).
