I have both cars and try to run them side by side as much as possible.
I like both cars very much. I'm a very average driver and I've found that the Durango feels/looks the faster car on the track (could be the noise it makes), its very aggressive and does handle well.
However, my 511 is such a smooth car on the track, it almost looks slow but I'm always more consistent and put in faster lap times even though it feels slower than the Rango. Does that make sense?
Have a chat with the boys at Bury, I'm sure you will get all sorts of reasons to buy one car over another but which ever one you go with you will not be disappointed as they are both excellent. I personally would go with the car that you can get the most assistance with track side with things like set-ups.
One thing to take into account though, if you get a Tamiya first and decide its not for you the second hand value for the car will be quite strong and you won't have any trouble in selling it on if you feel the need to compared to the Durango at the moment.
thats my 5p worth anyways..
