BMW M4 Cabrio Competition (F83) • 2020
Model series code: F83 • Engine: S55 3.0 biturbo • Transmission: 7-speed DCT • Drivetrain: RWD
Quick Overview
Purchased at a US auction on 13 March 2025. After arrival we carried out complete diagnostics, addressed all issues, and prepared the car for the European market (coding/programming, km/h speedometer scale). Installed a new intercooler, changed oil and filters, restored missing components, and performed numerous preventive maintenance tasks. The car is technically sorted and ready to enjoy.
Transparent history
Upon receipt we noted a cracked transmission oil pan (impact during driving) and a crack in the engine oil pan, plus several missing parts ("borrowed before the auction"): carbon strut brace, primary catalytic converters/downpipes, iDrive screen, keyless receiver antenna, and charge pipes (turbos → intercooler). All required parts were sourced and professionally installed.
