Known repair windows
What 348 Spider owners actually run into
Mileage ranges where these repairs typically show up. Buying above a window is not automatically a pass - it just needs to be priced in.
Engine-out timing belt failure (if neglected)
high severityAny mileage · $10,000-$25,000 (valve/engine damage)
Single belt carries both banks; interference engine, catastrophic if it slips.
Exhaust header / manifold cracking
medium severity40,000-80,000 mi · $2,500-$6,000
Thin headers burn through from heat; triggers CEL and exhaust leaks.
Cooling system / overheating
medium severityAny mileage · $1,000-$4,000
Radiators, fans, hoses; 348s run hot when cooling is tired.
Electrical gremlins (fuses, harness, alternator)
medium severityAny mileage · $500-$3,000
Climate-control 30A fuse, door-jamb harness pins, starter solenoid are recurring 348 faults.
