If you don't need to rush, then don't feel pressured into dropping the price.
I think it is way under priced for a late year VVTi, but like someone said, you need a buyer who understands the difference between a late facelift VVTi and an early J spec. Main problem is that there are plenty of young buyers with a £5 - £6k bank loan burning a whole in their pocket, and much fewer **usually** older buyers with the budget for a late facelift VVTi, and therefore, the cheaper cars turnover quicker.
I didn't drop the price on my VVTi TT6, and eventually a buyer came along. When he did, he knew exactly what he was looking at, had looked at a couple of tired examples from the trader, and the quality of a well maintained, well loved car closed the deal.
Hang in there, the right buyer will come along, and definitely don't give it away!
