The BMW 3 Series has never needed much of an introduction — for decades it has quietly defined what a driver’s sedan should be. But in a market crowded with hulking SUVs and futuristic EVs that look like props from a sci-fi film, the humble 3 Series is easy to overlook, and that might actually be the point. Whether it’s a workaday diesel or a rare homologation special built in tiny numbers, the 3 Series has always offered something genuinely special at a relatively accessible price. Icons earn that title for a reason, and a well-kept example — new or 20 years old — still turns the right heads.

These days, the 3 Series lineup has narrowed considerably. BMW currently offers the 225-horsepower 330i and the M340i, which packs the legendary 382-hp turbocharged B58 inline-six. With the base car starting above $47,000, it’s worth asking whether your money might work harder elsewhere.

All prices for this article are from Classic.com and Hagerty.com. The pictures are for illustration only and may not always relate to the exact model year. HotCars took the base price of the 3 Series and looked for sleepers from 2000 onwards. The results are in order of cheapest first.

2003 Audi RS6: $18,198

The C5 Audi RS6 arrived in America for 2003 as a sedan, rather than an Avant wagon like in other markets. While we may take wildly powerful performance sedans for granted these days, the RS6 was a trailblazer in that department — and its stats still hold up. This four-door packs all-wheel drive and a twin-turbocharged 4.2-liter V8 that produces 450 horsepower, channeled through a 5-speed automatic transmission to all four corners. The result is a 0–60 mph time of 4.6 seconds and a standing quarter mile in the mid-12s. The RS6 only lasted until 2004. Classic.com puts the average asking price for a 2003 model at $18,198 — meaning you could buy two for the price of a new base 3 Series.

2006 Mercedes-Benz E55 AMG (W211): $22,784

Mercedes-AMG

One of the mightiest super sedans of the 2000s, the W211 AMG still makes for an incredibly desirable car. The E55 AMG features a tuned chassis, subtle body kit, and a supercharged 5.4-liter V8 engine. Later AMG E-Classes looked meaner, but this version still very much flies under the radar, making it one of the all-time stealthiest sleepers. For the mid-2000s, the power output was eyebrow-raising: 469 horsepower and a substantial 516 lb-ft of torque. That’s enough to launch the AMG Benz to 60 mph in just 4.5 seconds. Classic.com puts the average price for a 2006 model at $22,784.

Pontiac G8 GXP: $24,700

Pontiac may have started the whole muscle car craze in the first place, but it sadly had to shut its doors in 2010 due to the economic downturn. But before this iconic brand disappeared, it left one reminder of how great its muscle cars were. When the G8 GXP arrived in 2008, it came fitted with a Corvette-derived, 415-horsepower 6.2-liter LS3 V8 under its hood. Along with all the executive amenities a middle-management buyer could want, the GXP delivered blistering performance — enough to keep pace with the V10-powered BMW E60 M5. With 415 horsepower and 415 lb-ft of torque, it sprints to 60 mph in 4.5 seconds and covers the quarter mile in just over 13 seconds at 109 mph. According to Hagerty’s Valuation Tool, expect to pay around $24,700 for a G8 GXP in good condition.

2013 Cadillac CTS-V Sedan: $34,250

Somewhere around the 2000s, Cadillac decided it was no longer going to just make cars for people to drive around Miami wearing Hawaiian shirts. The result was the V cars, a series of high-performance models that jumped right into the cage with the German super sedans for a proper bare-knuckle dust-up. Caddy didn’t disappoint either, especially with the second-gen CTS-V sedan, which was more refined than its predecessor and could be optioned with a manual gearbox. Power comes from a supercharged 6.2-liter LSA V8 producing 556 horsepower and 551 lb-ft of torque, sent to the rear wheels through a 6-speed Tremec manual transmission. Classic.com puts the average price for a 2013 model at $34,250.

2012 Lexus IS F (XE20): $34,648

The Lexus IS F arrived as a rival to the BMW M3 in 2007. True to the spirit of that era — when manufacturers were stuffing the largest engines possible into their performance cars — the compact Lexus sedan was powered by a 5.0-liter V8. It also comes with an 8-speed automatic gearbox featuring a manual mode with paddle shifters for drivers who want to stay involved. The IS F may look understated in the way only Lexus can manage, but underneath it’s an old-school muscle car in a business suit. With 416 horsepower on tap, it reaches 60 mph in a brisk 4.2 seconds. Classic.com puts the average price for a 2012 model at $34,648.

2016 Audi RS3: $37,411

The Audi RS3 channeled the spirit of the ur-Quattro, and not just because of its all-wheel-drive credentials. Arriving in 2015, the RS3 uses a turbocharged five-cylinder engine — just like the original — though this time it displaces 2.5 liters and produces a punchy 362 horsepower. Pair that with grip from all four wheels and a seven-speed dual-clutch automatic, and you have one of the quickest and most capable hatchbacks available for cross-country duty. A 2016 model now averages $37,411.

2010 Bentley Continental Flying Spur: $39,522

The first-generation Bentley Flying Spur arrived for the 2006 model year and was one of the British brand’s early models under Volkswagen Group ownership. These sleeper sedans are brimming with luxury and are powered by a crushing 552-horsepower 6.0-liter twin-turbo W12 engine, with all-wheel drive and a 6-speed automatic transmission. The sprint to 60 mph takes around 4.5 seconds, and the Flying Spur will keep pulling all the way to 200 mph. These cars represent remarkable value today, with even later 2010 models averaging just $39,522.

2021 Kia Stinger: $36,500

If you’re after a relatively recent sleeper without spending a fortune, the Kia Stinger deserves a serious look. This mid-size fastback draws stylistic comparisons to the Audi A7 and comes equipped with a potent twin-turbocharged V6 producing 365 horsepower and 376 lb-ft of torque, with a choice of rear- or all-wheel drive. It’ll reach 60 mph in approximately 4.7 seconds. Used values remain very accessible, with a 2021 model averaging around $36,500 according to Classic.com.

2017 Audi S8: $44,750

The S8 (D4) arrived for the 2012 model year fitted with a twin-turbo 4.0-liter V8, stepping back from the Lamborghini-derived 5.2-liter V10 that powered the previous generation. Along with the new engine, Audi also revised the suspension and chassis to match the car’s performance potential. The D4 S8 has to be one of the best used performance car bargains of recent memory. A car that cost around $100,000 new can now be had for an average of $44,750 for a 2017 model — that’s an extraordinary amount of car for the money.

2016 BMW M5: $45,450

BMW dialed back the drama when the F10 M5 debuted for the 2012 model year. Gone was the spine-tingling F1-inspired V10 of the previous model, replaced by BMW’s S63 unit. This may only be a 4.4-liter twin-turbo V8, but it is ferociously effective. The eight-cylinder produces 553 horsepower and 502 lb-ft of torque, sent to the rear wheels through a 7-speed dual-clutch automatic. The result: a 4,300-pound luxury sedan that reaches 60 mph in 3.7 seconds. Expect to pay around $45,450 for a last-of-the-line F10 M5.
