Golf R Estate
Well stuffed GTi if you like 2WD/FWD instead of 4WD.
If you are after RWD it becomes more interesting
C43 as Peter mentions.
If you can find a good condition older C Estate with the 6.2L natural V8 that was wicked
The W212 E63 previous shape was a loon and built well in saloon or estate, possible too much heavy metal?
BMW M135i with some bits from Birds (suspension and LSD) to enhance the ride and response
