From an enthusiast perspective? Yes, always desirable.

From a financial investment perspective? You are literally better off placing the money under a mattress for the next 20 years and then selling it to collectors because physical money is a novelty.

Any car that was produced in attainable numbers, even as low as a couple thousand units is not worth what was paid for it brand new unless there are extenuating circumstances (i.e. they melted away or this is a special unit). At best you could sell a Toyobaru for what was spent on it new (inflation adjusted) in about 50 years, everything I've seen points to that number working out from 911's and Corvette's and Mustangs and Sprites and TR6's to cars that are halfway through that age curve like Miata's and RX-7's and AE86's and 911's and Corvettes Mustangs.

You wanna make money buying and selling one of these as a classic? Sell what you've got now, buy a car from the 80's-90's give or take a few years (Miata, Trans-Am, Miata, Mustang, Miata, RX-7, Miata, AE86, Miata, MR2, Miata, 240sx, MX-5, GTV6) for around $5k, keep it mint for the next 20 years, sell it for a fat profit as the kids of that decade hit mid-life crisis and buy a ~20 year old Toyobaru at under $10k (or slightly higher because inflation), hope fossil fuels are still relevant and sell that 20 years later.

1965 911 MSRP ~$6k
50 years later top condition car is ~$40k
Inflation adjusted $6k 50 years later is $37.2k
at 60 years later, low condition cars are >$100k and up to $300k for special ones
And if that money was stuck in an index fund it'd be up in the $150k range guaranteed after 60 years.

The real trick is to go back in time and pick up a decent longhood 911 (or 'vette) for $500 in the 80's, I'm sure there are guys here who saw cars like that with those prices and those cars are now worth well into six figures.

There's data for the 1985 Supra, which MSRP'd for about $16k, 30 years later a top condition car is worth at best $17k, I won't bother doing the inflation adjustment to tell you how much that car is in the hole for somebody holding onto it as a collector car. However you can pick up decent ones for <$10k now, fix it up and hold out for 20 years, much safer investment than the toyobaru.

My money would be on early RX-7's and MR2's, both novelty cars, both performers, both dirt cheap right now (i.e. lower than what was paid for them in the 80's brand new).
