Specs side by side
What owners say
R8
Overall
Extremely positive sentiment regarding the driving experience, emotional appeal, and V10 engine character, with the vehicle widely described as a childhood dream car. The R8 is praised for its engaging, analog feel, particularly in earlier generations, and its relatively accessible supercar ownership experience. However, owner discussions reveal significant and recurrent concerns regarding specific reliability issues, most notably with the magnetic ride suspension and the air conditioning compressor.
Best version to buy
For the first generation (2008-2015), a later model year (2014-2015) V10 with a manual transmission is frequently cited as the most desirable and reliable combination. The manual is strongly preferred over the earlier R-tronic and S-tronic automated manuals for longevity and driving engagement.
Known issues
- ⚠Magnetic Ride Suspension Failure: Struts and shocks are prone to leaking, leading to complete system failure. Replacement with OEM parts is very costly, leading many owners to plan for aftermarket coilover upgrades.
- ⚠Air Conditioning Compressor Failure: Affects both V8 and V10 engines in the first generation. The compressor's location between the engine and firewall makes replacement a major, engine-out service, resulting in extremely high repair costs…
- ⚠Automated Manual Transmission Problems (R-tronic/S-tronic): Issues with early automated manuals in the first generation are noted as problematic and expensive to repair. Jerky shifting behavior is also commonly reported.
MP4-12C
Overall
Sentiment is sharply divided, creating a high-risk, high-reward ownership profile. The vehicle is widely praised for its stunning design, exceptional handling characteristics, lightweight chassis (~1,300 kg / ~2,866 lbs), powerful brakes, and surprisingly comfortable interior suitable for long-distance travel. It is recognized as a groundbreaking model that established McLaren's modern road car lineage.
Best version to buy
Insufficient owner data available to designate a specific model year or trim as "best." However, there is a strong, recurrent recommendation to seek out later-production examples (e.g., 2013-2014) and cars with higher annual mileage (2,000-5,000 miles per year) as they are believed to have had early gremlins addressed under warranty and suffer fewer issues from sitting idle.
Known issues
- ⚠Electronic system malfunctions: Infotainment (IRIS) screen touch failures, system freezes requiring reboots, climate control LCD screen failures, "key not found" errors, various warning lights. Frequency: very frequent.
- ⚠Hydraulic system accumulator failure: PCC (Pneumatic Control Circuit) errors, suspension mode change failures; consumable items needing replacement every 2-4 years at a cost of approximately $1,400-$5,000. Frequency: very frequent.
- ⚠Transmission concerns: Reports of complete transmission failures requiring replacement (costing ~$30,000), though some owner discussions suggest this reputation may be overstated and linked to warranty repair practices rather than inherent…
