Drive a Porsche, and you will be amazed at how good it actually is, even such simple things as steering feel. It's so communicative and compared to the the VAG sh*te we are driving, being behind the wheel of a Porsche from a VAG is like going from analogue TV to HD.
It's just artistry, I swear I could cry everytime time I got to drive my mates, it's just filled me with emotion and joy lol.
The only draw back I could conclude from it though, is that the Porsche could get tiring over long distances. But my god what a car.
TBH we can't make the decision for the OP's brother, I'm sure once he's driven both he will know exactly which one he prefers. Both are awesome, both are basically as fast as each other, and both have a good road presence and will now hold their value fairly well. (Unlike a new Golf R no matter what deal they give you)
