What owners say

675LT

Overall

Sentiment is highly polarized, split between owners who report an exceptional, reliable driving experience and those who report persistent, debilitating reliability issues. The vehicle is universally praised as a phenomenal driving machine, described as a "peak" model for the brand, a "beast," and one of the best-driving cars on the road even years later. Its driving dynamics, lightweight construction, and raw performance are celebrated.

Best version to buy

Insufficient owner data available to declare a definitive "best" version. Limited feedback suggests coupes with the roof scoop and louvered fenders are the most sought-after configurations for collectibility.

Known issues

  • Persistent electronic system failures: includes traction control errors, TPMS faults, ABS faults, power window malfunctions (can prevent door operation), key recognition failures, driver display and infotainment screen freezes, and complet…
  • Hydraulic suspension accumulator failures: components wear out, typically every 1-4 years depending on use, causing PCC errors and preventing suspension mode changes. Frequency: very frequent.
  • Infotainment (IRIS) touchscreen failure: screen becomes unresponsive or fails; replacement is costly ($2,000-$4,000 USD). Frequency: recurrent.

720S

Overall

Sentiment is sharply divided, creating a high-risk, high-reward ownership profile. The vehicle is universally praised for its staggering performance, with owners describing it as an "absolute savage," "the fastest of the bunch," and offering "the best ICE performance" in its segment. The driving experience is noted for being incredibly engaging, with exceptional handling, grip, and braking performance that is frequently compared to a race car.

Best version to buy

Insufficient owner data available to declare a consensus "best" version. Owner discussions mention later model years (2020-2021) having better software packages that resolved some electrical glitches present in 2018-2019 cars.

Known issues

  • Poor reliability and frequent mechanical/electrical failures: very common issues include infotainment module failures, failing suspension accumulators, cracked springs, squeaking/worn front bushings, dead accumulators, rattling downpipes,…
  • Low-quality interior materials and build quality: interior described as feeling cheap, using excessive hard plastic, suffering from squeaks and rattles, and having buggy infotainment software. Frequency: very frequent.
  • Rapid depreciation and poor residuals: value sinks faster than competitors due to reliability reputation and high production volumes, making it a poor investment. Frequency: very frequent.
