The One Classic Most Buyers Should Target First
Classic cars appreciation refers to older vehicles whose values are rising over time due to desirability, limited supply, engineering quality and shifting tastes among enthusiasts, making them credible collector car investment opportunities rather than simple nostalgia purchases. For most buyers, the single smartest starting point is the BMW E39 M5. It combines everyday usability with the mechanical feel enthusiasts are chasing as modern cars become dominated by electronics and software, and demand for these analog German performance icons is already rising. Some of the strongest collector car investment options are discreet German performance sedans rather than flashy supercars, and the E39 M5 sits right at the heart of that trend. If you want one classic that still works as a family car, rewards skilled driving, and has clear upside before total market saturation, this is the one to prioritize.
BMW E39 M5: Peak BMW and a Clear Value Climber
The BMW E39 M5 worth watching today is the well-kept, original-spec car that shows the model’s “sleeper” character: subtle bodywork, quad exhausts and an understated cabin that looks close to a regular 5 Series but hides serious pace. Its naturally aspirated 4.9‑liter V8 and six‑speed manual deliver the kind of feedback and driver involvement that modern turbocharged, software‑managed cars struggle to match. Industry observers expect a collector wave through 2026 focused on analog performance icons with everyday usability, placing the E39 M5 directly in the spotlight. German Analog Icons Are Appreciating For Good Reason, and this car is already seen as one of the greatest sports sedans ever built. Backed by strong parts support and independent specialists, it remains practical to own, which further underpins classic cars appreciation and makes it my top pick for long‑term value.
Used Porsche 911s: Proof That Timing Is Everything
If the E39 M5 is the obvious buy‑now candidate, used Porsche 911s are the clearest warning that you cannot wait forever. Enthusiast demand has pushed values of almost every generation upward, from early air‑cooled cars to the once‑affordable 996 with its controversial “fried‑egg” headlights. According to a large iSeeCars study, average prices for three‑year‑old 911s have risen far faster than for most other used luxury cars, confirming how strong this platform’s pull has become. The boom is not limited to halo GT3 or Turbo variants; heightened interest in special editions has lifted more modest specs as well. For investors, this shows how quickly an undervalued enthusiast car can move from hidden gem to expensive mainstream collectible. The lesson is clear: the best collector car investment is the one you buy before everyone else notices the same trend.
Divisive Designs That Became Smart Long-Term Holds
Some of the most promising used luxury cars value plays are the designs people once disliked. Cars such as the Audi A2, BMW E60 5 Series, Porsche 911 996, Citroen C6 and Renault Avantime all divided opinion, struggled to find buyers or seemed far ahead of their time, but they have aged far better than anyone expected. Their once‑odd shapes now read as distinctive and restrained compared with busy contemporary styling, and their engineering stories—a lightweight, efficiency‑obsessed A2 or the bold E60 saloon—are gaining appreciation. These are not yet blue‑chip investments, but this is exactly the phase where timing matters most: before they become mainstream targets. As enthusiasm grows for analog, characterful designs, the best returns will go to buyers who recognize the pattern early and secure clean examples while they remain relatively overlooked.
Buy if / Skip if
- Buy the BMW E39 M5 if you want one classic that combines daily usability with clear appreciation potential among analog performance icons.
- Skip the BMW E39 M5 if you are unwilling to budget for maintenance in line with its original luxury performance status.
- Buy the used Porsche 911 if you already understand rising values and care more about long-term desirability than short-term affordability.
- Skip the used Porsche 911 if you are hunting for a bargain sports car rather than a collector car investment that is already expensive.
- Buy the once-divisive Audi A2, BMW E60 5 Series or Porsche 911 996 if you believe distinctive design and engineering will keep outperforming newer, flashier models.
- Skip the Audi A2, BMW E60 5 Series and similar cars if you dislike unconventional styling and prefer contemporary models with heavier digital features.
