When this article was first published in 2023, we highlighted five cars that appeared to have the ingredients collectors often look for: rarity, distinctive design, enthusiast appeal and increasing scarcity.
Several years later, those same qualities still make these cars interesting to enthusiasts, but predicting future values is never guaranteed. Condition, originality, mileage, service history and changing demand can all have a significant effect on what an individual car is worth.
Rather than treating these models as guaranteed investments, we’ve revisited the original five to look at why they attracted attention, what makes the best examples desirable and what buyers should consider today.

1. Audi TT Quattro Sport MkI
Why collectors liked it
- Limited-run model
- Lightweight version of the original TT
- Distinctive Bauhaus-inspired design
- Strong turbocharged engine and quattro AWD
Investment outlook
The first-generation TT had already become a modern design icon. The Quattro Sport version added rarity and enthusiast appeal, which tends to support long-term values.
Watch for
- Original specification
- Low mileage
- Full service history
- Unmodified examples
2. Austin Seven
Why collectors liked it
- One of Britain’s most important early cars
- Simple mechanics
- Affordable entry into vintage motoring
- Huge historical significance
Investment outlook
The Austin Seven is often considered one of the best “starter classics.” Values usually rise steadily rather than dramatically.
Best examples
- Original bodywork
- Strong provenance
- Pre-war authenticity
3. Bentley Turbo R
Why collectors liked it
- Hand-built luxury
- Massive turbocharged V8
- 1980s/90s prestige appeal
- Growing appreciation for analogue luxury cars
Investment outlook
For years, the Turbo R was relatively affordable compared with many other prestigious classics. As surviving examples have become older and scarcer, its combination of traditional Bentley luxury and turbocharged performance has attracted increasing enthusiast interest.
Biggest risks
- Maintenance costs
- Rust
- Neglected suspension systems
A cheap Turbo R can become very expensive quickly if poorly maintained.
4. Citroen BX
Why collectors liked it
- Distinctive 1980s styling
- Famous hydropneumatic suspension
- Increasing nostalgia
- Extremely usable classic
Investment outlook
The BX was never expected to explode in value, but clean examples became increasingly scarce. Enthusiasts began recognising it as an underrated modern classic.
Best versions
- GTi
- 16 Valve
- Diesel estates in excellent condition
5. Ford Fiesta MkI
Why collectors liked it
- First-generation Fiesta nostalgia
- Lightweight and simple
- Early hot hatch culture
- Rising values for XR2 and Supersport models
Investment outlook
As many ordinary Mk1 Fiestas disappeared from UK roads, surviving clean cars became more collectible.
The performance variants were already climbing sharply, but standard cars also started following the trend.
What Usually Makes a Car Increase in Value?
These factors matter most:
| Factor | Why It Matters |
|---|---|
| Rarity | Fewer surviving cars = stronger demand |
| Originality | Collectors prefer factory-spec cars |
| Condition | Rust-free examples command premiums |
| Service history | Proof of care increases confidence |
| Enthusiast demand | Strong owner communities help values |
| Historical importance | “First”, “last”, or iconic models attract buyers |
For collectible and older cars, documented servicing can be particularly important. A consistent record of maintenance, repairs, MOTs and supporting invoices can help demonstrate how a vehicle has been cared for throughout its life. Our Service History & Vehicle Records hub explains what records are worth keeping and why they matter.
Why Some Modern Classics Continue to Attract Collectors
Enthusiast cars can become more desirable as good examples become harder to find. Distinctive design, an engaging driving experience, limited production and a strong connection with a particular era can all contribute to long-term collector interest.
That doesn’t mean every older or enthusiast car will increase in value. The individual car still matters enormously, particularly its condition, originality, mileage, provenance and service history.
And if you’re considering holding onto a classic that might appreciate, this guide on storing a classic car explains how proper storage can protect and even enhance long‑term value.
If You’re Buying as an Investment
The safest strategy is usually:
- Buy the best-condition example you can afford
- Prioritise originality over modifications
- Look for full history and documented maintenance
- Avoid neglected “cheap” examples
- Store and maintain the car properly
Running and maintenance costs should always be considered alongside any potential change in value. Older and specialist cars can require expensive servicing, repairs, storage and insurance, so buying purely in the expectation of making a profit carries risk.
It’s also worth understanding why most cars lose value over time. Our guide to car depreciation explains some of the factors that influence depreciation and residual values.
Best “Affordable” Future Classic from the List
There is no single answer, because values and collector tastes change over time. For buyers working with a more modest budget, the most interesting cars are often models with a strong enthusiast following, distinctive character and a shrinking supply of original, well-maintained examples.
The Ford Fiesta Mk1 from our original list is a good example of that principle. But whichever model you’re considering, buy primarily because it’s a car you would be happy to own and enjoy — any future increase in value should be treated as a possibility rather than a certainty.
How Much Is Your Car Worth Today?
Whether you own a potential future classic or an everyday car, its current value depends on factors including age, mileage, condition, specification and market demand.
