It is an interesting and not a simple question to ask.In the UK, seems that Vanquish prices have held over the last year and actually gone up a small bit. Do you think the trend will continue or will early cars start depreciating again towards the end of the year?
So far I would say that the prices would continue to go up.
This is because the Vanquish started to depreciate progressively as new, more refined Astons have come out in the last years or so.
Initially customers were looking for better build quality, a more refined powertrain (in terms of the transmission), and cheaper cars that Aston offerred after the Vanquish, so the value of the Vanquish dropped heavily once the DB9 and later the V8 vantage got popular.
However now, the Vanquish can be regarded as more of a classic model than an old model with newer/better/cheaper models in the lineup. It has the looks that would distinguish it from the current Aston lineup and the "former flagship car" image that would result in the customers forgiving its faults. Plus the fact that it hs not been in the media much lately (since it is not in production) make it seem much more exotic than the "more commonplace" DB9 (which is itself aging).
I could be wrong, but I think that the manual (final edition) versions of the Vanquish S might even fetch more than a DBS sometime soon, with the S in general appreciating well.
And, again I do think that the Vanquish prices would increase slowly untill 2013, then drop slightly (new lineup introduction), and then continue to increase with little disruption afterwards.
