It has to be the Mercedes E63 AMG Estate (Wagon) for me
"The E63 AMG Estate is powered by a variant of the high performance hand built 6.2 Liter AMG V8 that delivers 525 HP, 11 HP more than the previous model, which is enough to send the estate from 0 to 60 MPH in 4.6 seconds, and reach an electronically limited top speed of 155 MPH, or 173 MPH with the optional AMG Driver’s Package,"
