My thoughts are a 300bhp GTI with WALK (or equivalent), engine mounts, decent tyres (GY F1's), lowered and importantly: LINEAR THROTTLE MAPPING, would be great fun to drive. Even better with LSD!
You could use most of the power most of the time and have a lot of fun whilst doing so
The Golf R and S3 as standard are very "safe" but not very exciting, 260ish bhp is EASY for the 4WD system to handle day to day so you need to ramp it up to high 300's or into the 400bhp range to liven it up, get the tail out etc
