In terms of quickess and in general, I wouldn't say no to a TT-RS... I almost went for a TTS but even second hand I thought too much money for the mileage. No one could argue the TTRS isn't quicker, its blistering and more so when modded. You choose the Zed for a number of different reasons, mainly...the way it feels. All that clunkyness and raw noise and barn door way it puts its power down makes it feel special, different..old skool. Some people like that some people don't. You won't get that in a TT-RS... you'd love it I think, I prob would had I got one, but I would never regret the Zed.... its a nice car to say you've owned and experienced..even if it keeps breaking bushes and exhausts and other stuff pml
