Ah right, yep i was looking at the 1.9D also, but at that time (Dec 08/Jan 09) they weren't available as demo cars, and when i worked out the fuel (for the mileage i do), offsetting the extra cost in diesel against better mpg in the diesel, and the fact the diesel was £600 more at the time, i came to the conclusion that it would take me 2.5 years to reap any benefits in diesel vs petrol. But for the miles you do, diesel is a much better choice !
When i bought my 1.6S it was a demo car with the SEAT garage, with 1800 on the clock, and i got £2400 knocked off, which was a pretty good deal i think, and it had BlueTooth Radio, Digital Climate Control, 17" alloys and black metallic paint, so it was perfect for what i wanted. Demo cars are a good buy as they are usually well looked after, being owned by SEAT.
