looking C63 AMG - info

[Torquecars]

Hi there, i am looking for a C63 AMG but would like to know if there are any issues such as head bolts that i should be aware of....i would definitely want PPP and piece of mind with a warranty and expect the cost of fuel and rear tyres to be high but just wonder how they compare with an M3 as a daily useable car...any comments appreciated....thanks
