Interesting thoughts; but I do wonder if as a car gets older 'low mileage' reduces as an essential to value and that 'overall condition' becomes more important. I believe that the GTV/Spider does have what it takes to 'become a classic' but ultimately, imo, it's scarcity that helps increase values increase. But don' expect values to increase anytime soon; it's only quite recently that GTV6s have started to increase in value.
I think V6 GTVs will hold their prices and may even increase slightly whilst TS will continue to disappear at a rate of knots because non Alfisti owners don't consider them worth repairing properly eg belts etc.
I remember a similar situation with Lancia Fulvias; I was looking for one in the mid 80s, and many I looked at had rotten subframes and as a result were scrapped and now there are hardly any on the road.
My advice for anyone thinking of buying a GTV is, yes get one, they drive well, are comfortable enjoy it for what it is a great sports coupe; but don't expect an immediate return on your money.
I agree completely. I bought an Uno Turbo for $2000 when I got my first job in 2002. It was an original car but a bit rotten in a few places (floor, sills). I fixed it up (or got it fixed up, my welding being of limited quality). I then made a few non-original mods. Such as, replacing the tent-like sagging headlining with speaker box carpet.
I owned that car for over ten years and eventually sold it last year. It went overseas to Perth (very unusual to export cars from NZ to Australia). I got a fair price of about $3000 for it - could have been even more but I took pity on the friend-of-a-friend who faced considerable costs getting his collectors-piece home. I understand there are only 18 Mk1 Uno Turbos left on the road in England out of 7000+ sold.
The motto here; what was once an example in only average condition and not completely original became better-than-average (as you said). And it cost me almost nothing over all those years. My only regret? I wish I'd spent a bit more and bought a better one in the first place.
In my opinion, it doesn't have to be a limited edition model to become rare and valuable. After all, they only made 1,429 phase-2 V6 Spiders - how limited is that anyway?
