Vehicle Details
AI Listing Summary
This 2015 BMW M4 coupe is a meticulously built track car featuring extensive GT4-style modifications by BimmerWorld, including upgraded engine components, suspension, and aerodynamics. Despite its track-focused nature and 63k miles, it presents as a well-maintained vehicle with a clean Carfax report, though some advanced driver assistance systems are non-functional.

Condition
7
The car is a modified track car with 63k miles. While it has undergone professional upgrades and has a clean Carfax, it has been used for track events (SCCA HPDE). Some factory amenities like blind-spot monitoring and Active Driving Assistant do not work, indicating it's not in perfect or near-perfect condition. However, the upgrades and overall build suggest it's well-maintained for its intended use, placing it in the 'Very Good' category with potential for minor reconditioning.
