At the end of the day the market will decide the value, if it sells it is worth the money
Yeah agree with you on this
I think older ultra low miles cars in really top condition, will always command a high premium as you will always have someone wanting a low miles best possible example of a particular model that they can find, and the older the car gets the harder these good examples are to come by, so when they do turn up, someone will generally cough up the cash
It might take a while to sell as it's a much smaller market, but sooner or later someone will come along as there is just not the choice available on older cars that you get on newer ones in terms of good available examples.
I owned my 159 around 2 weeks and it took me around 6 weeks to find a good lowish miles V6 at a good price, and this is a car that is only 7 years old, a couple of nice low miles dealer cars cropped up during that time, but i was confident i should be able to get a good private example at a good price if i waited. I doubt you have that option on a GTV 3.2 unless your prepared to wait a lot longer than a few weeks.
And that's the rub, the older the car, the less chance you have of finding a really good one at a great price, so the price you do have to pay for a good one really starts to go up
