Not every collector car costs six figures. Some rare gems are still affordable today — but maybe not for long. Here are 10 underrated cars you can still find for under $20K that may shoot up in value over the next few years.
1. Mazda RX-8 (2004–2011)
Unique rotary engine, lightweight, and sporty. Prices are still low due to engine quirks, but enthusiasts love it.
2. Acura Integra GS-R (1994–2001)
A true JDM legend with a rev-happy VTEC engine. Clean, unmodified models are getting harder to find.
3. BMW E46 330Ci ZHP (2003–2006)
The “hidden M3.” Great engine, rare trim, and rising demand for clean examples.
4. Volkswagen Golf R32 (2004, 2008)
Limited production, AWD, VR6 engine — a collector sleeper.
5. Toyota MR2 Spyder (2000–2005)
Mid-engine roadster with go-kart vibes. Lightweight + rare = rising prices.
6. Saab 900 Turbo (1984–1993)
Weird, boxy, turbocharged — everything a future classic needs.
7. Lexus SC300 (1992–2000)
Reliable, RWD, and shares DNA with the Supra — potential tuner gold.
8. Ford Mustang Bullitt (2001, 2008)
Special edition Mustangs with limited production and cult status.
9. Subaru SVX (1992–1997)
Funky window design, AWD, and only around 25K made in the U.S.
10. Honda CR-Z (2010–2016)
Manual hybrid? Yes, it exists. Low production, high future value.
Final Thoughts
If you’re into spotting rare rides or collecting future classics, these cars are worth watching. Many are still under $20,000 — for now.
