If he was that level with you, then he wasn't trying. The TTRS is fast as fook, and I'd do well to keep one honest in the 911.
336bhp, 4.6 0-60. So not hugely more than the 313 zed in the real world. Maybe he wasnt trying, but seems strange that he followed me for 8 miles, waiting for me to put my foot down, then when we did have a bit of fun he wouldnt try. Either way, they are very nice cars and very tuneable. But for £40k you are spoilt for choice really as to what incredible cars you can buy.
4.6 to 60 is about a second quicker than the zed which is a lifetime, plus it is lighter, 4WD and with more BHP. Theres no shame in it being quicker than a zed due to being about £20k more when new......
