What owners say
Z4
Overall
Sentiment is highly dependent on the specific generation and powertrain. For the current generation (G29), the Z4 M40i variant receives extremely positive feedback from owners, described as "insanely good," "stupid fast," "incredible power," "balanced," and "the best car I've ever owned." It is praised for its fun factor, driving dynamics, and value proposition, particularly when equipped with a manual transmission. The base 30i variant is considered competent but less memorable, with some reviewers labeling it "forgettable." The previous E89 generation (2009-2016) is viewed more as a comfortable grand tourer or "Palm Beach cruiser," with criticism for feeling heavy and sluggish.
Best version to buy
For the current generation (G29), the Z4 M40i is overwhelmingly recommended as the definitive version. Owners emphasize that the high-output B58 engine transforms the experience, making it "exceptional" and a "real weapon," whereas the lower-powered 30i variant does not leave the same impression.
Known issues
- **E85/E86 & E89 Generations:** Cooling system failures (water pumps, expansion tanks): common point of failure. Frequency: recurrent. Oil leaks (valve cover gaskets, oil filter housing): common with age. Frequency: recurrent.
- **G29 Generation:** Factory brake fluid inadequacy: noted as unsuitable for the car's performance level. Frequency: isolated. "Ass-backward" tachometer design: criticized layout. Frequency: isolated.
Elise
Overall
Extremely positive sentiment among owners, characterized by an almost universal appreciation for its raw, engaging, and pure driving experience. The vehicle is consistently described as providing an unparalleled connection to the road, with exceptional steering feel, a communicative chassis, and a thrilling sense of lightness. Owners frequently use superlatives to describe the fun and excitement of driving, often comparing the experience favorably to far more expensive supercars when modified.
Best version to buy
Insufficient owner data available to declare a consensus "best" trim or edition. Discussions indicate strong interest in the Series 2 (S2) generation, particularly US-market models from 2005 onward.
Known issues
- Spartan and uncomfortable nature: difficult ingress/egress, firm ride, lack of sound deadening, minimal storage space, cabin noise. Frequency: very frequent.
- High cost of body repair: damage to the large fiberglass clamshell body panels is described as very expensive to repair or replace, with paint matching being a particular challenge. Frequency: recurrent.
- Engine-specific concerns (Rover K-series): head gasket issues are widely discussed, though some owners note most cars have had this addressed; also noted to burn oil and has multiple belts requiring service. Frequency: recurrent.
