Still maintain that the 3200 will rise more than the 4200 in the next 5 years...
The market for the 3200 is all over the place. Market top end for non AC cars is knocking on the door of £30k, while some struggle to make £10k at ACA. And £10k still isn’t bottom of the market.
Even though I love the car it’s tricky to make that call from an investment POV - once the bottom of the market solidifies and the sub-£10k cars disappear then the top can rise. The 4200 is rarely dipping below £15k and the best cars are advancing already. There’s just too much variation for the 3200 - at the moment.
It was the case for the Porsche 928 and the BMW 635 CSI - look how long it’s taken those to shake off the lower end of each market. The 3200 will increase but those expecting to double their money may be disappointed.
On a personal note I’d never buy a car for just investment purposes - I see value rises as an added benefit. Buy the car you love and if it still makes you happy then your investment in your own joy will pay off, and leave the balance sheet to the accountant.
