Classic/collectable/sought after cars to put away now.

[Barni]

Hi peeps, my first post here as I needed some advice as this has been a recent discussion topic with some friends. My apologies if this topic has been brought up previously, I did search through 4 hours prior to typing but there is a lot of info to get through.
Our discussion is what car would be put away which has the best potential to perhaps increase in value over the next 15-20 years, whilst enjoying the car on the rare special occasion. This was brought up especially as ford and Holden are closing locally, and we believe nostalgia will kick in when it does down the track.
We have other cars that we drive regularly, and storing money in a bank at around 3% is crap. We have other investments as I know most will say invest in something else, but for the sake of this topic could we agree it has to be cars. We discussed that cars with race pedigree mean something, but other cars do become sought after also if well maintained with low km's. Some cars we brought up are the FPV GT cobra which I love, FPV gt 40th edition, boss 355 r spec, FPV GT-F, HSV coupe gts, coupe 4, cvz8 Monaro...
(I reckon there are to many but it's been mentioned so I'll let you guys decide). Early 911's have increased already, porches 944's? It helps if the cars have depreciated and levelled off just prior to hopefully increasing. We don't have unlimited budgets so cars that most people can afford is what we have spoken about. Anyhow would be great if people could contribute the're thoughts on cars you would buy now if cash is available, on the best possible choices to buy. Appreciate the feedback.
