I'm not here to upset people as I enjoy being on here, but think some folks are a bit up their own arse and very biased with these cars, but it's like it on every forum.
The reason for the sudden price hike is that it is the middle of summer and everyone is chancing it. It'll be years before they truly go up in value for being desirable - they are still fairly common cars.
They are only worth what someone is willing to pay and looking at the prices they are currently at, no one appears to be buying. The same ones have been for sale for months.
I don't see anyone with their head up their arse. It's a forum and people speculate and have opinions. It's not all going to be spanners and oil.
I know many people don't care what their car is worth and that's fine. But there's plenty of people who need to justify the money they put into a car and like to have some notion of what it may be worth in the future.
I also think the idea that prices are inflated in the summer is not necessarily true. In my experience prices peak in March & April as people get ready for the summer and look to maximise the classic/2nd car Apr-Sep 6 month road tax window.
Come back end of June we are a third of the way through the summer months already and half the way through the road tax window.
That said I agree a number of cars are sticking around for a long time at the moment, especially 3.0s. Whether that's because they are over-priced I don't know for sure. I suspect people are still trying to get Spring prices when as I say, the market is actually cooling off right now. Possibly coupled with the cars not being quite as nice in the flesh as they are in the photos.
