BMW 3-serie — The Ultimate Driving Machine

Premium for everyone 

Since its debut in 1975, the BMW 3 Series has been the backbone of BMW's model range — and perhaps the car that best defines the concept of "driving pleasure" in the premium segment. Generations have succeeded each other, but the core values ​​have always remained: rear-wheel drive, precise steering and engines that want to rev. In the enthusiast world, the 3 Series has become the perfect platform for everything from daily drivers to track cars.

Generations of the 3-series

The first 3 Series. Replaced the BMW 02 Series and established the concept. Relatively rare today, but well-preserved examples increase in value. The 323i with its silky-smooth M20 six is ​​the favorite.

E30 (1982–1994)

The great cult classic. The E30 is the 3-series that really took BMW to the masses. Compact, light and with fantastic chassis balance. The 325i with the M20 engine is the "sweet spot" — but it is the E30 M3 (S14, 4-cyl) that is the crown jewel and sells for millions internationally. The 325i Touring and Convertible are also sought after.

E36 (1990–2000)

Bigger and more refined. Long considered "the boring one" but has been greatly re-evaluated. The E36 M3 (S50/S52) offers incredible performance at a reasonable price and many consider it to have better chassis balance than its successor. The 328i with its last iteration of the straight-six engine is also popular.

E46 (1998–2006)

A favorite of many enthusiasts. The last "analog" 3 Series with hydraulic steering and naturally aspirated engines. The E46 M3 with its S54 engine (343 hp) is considered by many to be the best M car ever. The 330i and 330d are also excellent drivers' cars. The convertible and coupé versions have an elegance that lasts.

E90/E92 (2005–2013) 

First generation with turbo engines (N54/N55). The 335i with the N54 twin-turbo is a hidden rocket — and the E92 M3 with its V8 (S65) is the last M3 with a naturally aspirated engine. A future classic without a doubt. The E92 335i Competition and the rare M3 GTS are also sought-after collector cars.

F30/F32 (2012–2019) 

The sixth generation marked a clear technological leap towards more comfort and digitalization. All engines turbocharged — the six-cylinder B58 in the 340i is considered by many to be one of BMW's best engines in decades. The F80 M3 (S55, twin-turbo, 431 hp) is controversial among purists but delivers incredible performance. Adaptive suspension (M Adaptive), Active Sound Design and head-up display were new in the class. The F30 is considered by enthusiasts to be the last 3 Series with reasonable weight and a ready-to-drive feel.

G20 (2019–) 

The seventh and current generation is more technology-driven than ever — with a digital instrument cluster, advanced driver assistance and BMW’s latest CLAR platform. The G80 M3 (S58, 480–530 hp) is one of the fastest series-produced BMWs ever, but has met with biddershighway.com 2 mixed reactions for its controversial front design with a large kidney grille. Electrification has made its entrance with mild-hybrid technology in most variants. The G20 is still too new to have established itself on the classic track, but the first examples are starting to appear on the secondary market.

BMW 3-series on Bidders Highway 

The 3 Series is one of the best-selling models on the platform. With an average price of SEK 142,000 and prices between SEK 66,000 and SEK 680,000 — the latter for a BMW M3 Competition 30 Jahre (2017) — it is an accessible but broad path into BMW enthusiasm. Total sales: SEK 4.1 million.

Key figures & value

Buying guide: BMW 3-series

What to look out for?

- E30: Rust in wheel arches, sills, jack mounts and front fenders. Also check the tailgate and window frames. The timing chain on the M20 should rattle freely — not rattle.

- E36: ​​The cooling system is the Achilles heel — check the expansion tank, water pump leaks and thermostat. Subframe mounts can crack.

- E46: Subframe cracks (rear), vanos solenoid problems, cooling system (plastic parts cracking) and oil leakage from the valve cover gasket. 

- E90/E92 335i (N54): Wastegate rattle, injectors, HPFP (high pressure fuel pump) and charge pressure pipes coming loose. 

- F30/F32 (B48/B58): Check service history carefully — many were owned as lease cars and may have neglected maintenance. The N55 engine in early 335i is reliable but sensitive to oil change intervals. Check brakes and driveshaft boot. 

- G20 M3/340i (S58/B58): Relatively new and reliable, but check that service has been followed and that any software updates have been applied. Tire wear can be high in sport package configuration. 

- General: Check service history carefully — BMW engines reward regular maintenance and punish neglected service.

Recommended models/specs

- Best value for money: E46 330i/330Ci (2000–2006) — last straight six without turbo, wonderful to drive. 

- Cult classic: E30 325i (1985–1993) — compact, light, perfect chassis. Preferably manual with sports suspension. 

- Best investment: E30 M3 — prices rise every year. Original condition with documentation is gold. 

- Modern favorite: E92 M3 (2007–2013) — last V8 M3. Manual version especially sought after. 

- Turbo sweet spot: F30 340i (2015–2019) with B58 engine — incredible performance, relatively reasonable prices and exceptional reliability for a turbo engine.

- Top performance now: G80 M3 Competition (2021–) — 510 hp, 0–100 in 3.9 sec. Choose manual (XDrive or RWD) for the purest driving experience.

Tip 

- Aftermarket support bearings, control arm bushings and stabilizer bars are cheap but make a huge difference in driving feel. 

- Avoid cars with "M-sport packages" that don't have the right engine — the important thing is under the hood. 

- E36 and E46 are still very affordable, but expect prices to rise over the next 5 years.
