Specs side by side
What owners say
RL
Overall
Owners regard the RL as a comfortable, quiet, well-built luxury sedan with a strong V6 and a notably refined cabin, and several long-term owners report trouble-free runs past 200,000 miles. The dominant criticism is that the car is now old, parts are increasingly hard to find, and the early-2000s V6 automatic transmissions are a known weak point. Sentiment splits by generation: the first-generation 3.5 RL (1996-2004) draws praise for durability but warnings about transmission and parts scarcity, while the second-generation RL (2005-2012) is described as smoother, quieter, and better sorted, with the 2008 model specifically called out as having had early bugs worked out.
Best version to buy
Insufficient owner data available to declare a consensus. The strongest partial signal favors the 2008 model year, which owners describe as the point where early tech, radio, and SH-AWD issues were resolved, and the 2011-2012 RL is called an absolute unicorn by one owner.
Known issues
- Automatic transmission failure or slipping, particularly on early-2000s V6 models: Frequency: very frequent. Parts availability problems, including scarce dealer, aftermarket, and used parts: Frequency: very frequent.
5 Series
Overall
Sentiment is highly polarized and generation-dependent. For the latest generation (G60, circa 2024-2025), initial owner feedback is sharply negative, with strong criticism directed at its excessive physical size, the near-total removal of physical controls in favor of digital interfaces, and perceived lack of driving satisfaction, particularly in lower-powered variants like the 520d. In contrast, feedback on the preceding F10 (circa 2010-2017) and G30 (circa 2017-2023) generations is generally positive, with owners expressing love for their vehicles, praising them as excellent daily drivers that balance comfort, performance, and a high-quality, driver-focused interior.
Best version to buy
For the F10 generation, the 535i with the N55 inline-six engine is specifically recommended over V8 models (550i, 750i) due to its superior reliability and lower maintenance costs, making it a smarter choice for used buyers. For the G30 generation, the 530i is noted as having strong torque and not being slow.
Known issues
- Excessive size and lack of physical controls (G60 generation): criticized as too large and unsatisfying due to digital switches for even basic functions like airflow vents. Frequency: recurrent.
- High maintenance costs and unreliable engines (specific to older V8 models): the N63 V8 engine (in 550i/750i) is regarded as one of BMW's most unreliable, requiring expensive repairs.
- Digital interface and haptic feedback concerns (newer generations): buttons may not work in very cold weather (below -10°C / 14°F), failing to recognize touch with gloves. Frequency: isolated.
The verdict
The Acura RL is the better choice for most buyers.
It has stronger reliability sentiment in owner reports than the BMW 5 Series, based on the data above. If the specific known issues on the Acura RL are a dealbreaker, the BMW 5 Series is worth a closer look instead.
