Classic Cars That Are Becoming Investment Gold in 2025 (4 of 5)

6. Triumph Stag

While the Triumph Stag was praised for its style and comfort, it was an absolute dud during its brief 1970 to 1977 production run. Constant engine problems just made it far more trouble than it was worth. But thanks to upgrades and modern restoration techniques, the stylish Stag is now able to run the way it was meant to. Only around 26,000 units rolled off the assembly line, making it scarce enough to be valuable and relatively easy to find. 

7. BMW E24 6 Series

The E24 was a solidly engineered car back during its 1976 to 1989 production run, and it still holds true today. Comfortable and delivering sharp driving dynamics, you can corner at high speeds with ease or cruise on the highway with confidence. Best of all, since BMW’s new cars aren’t radical departures from their previous models in terms of engine design, it’s not difficult to service this classic car. For all these reasons, collectors love to drive this one around even as they keep the others parked in their garage.
