BMW M6 Gran Coupe.
What to Check Before Buying.

As a high-performance model with complex mechanicals, it can be expensive to run and maintain, particularly outside warranty. Buyers should focus on full service history, evidence of proper maintenance intervals, and signs of hard use or track driving.
