What's your budget ?
any specific reason why did you choose these rides ?
I can't comment about Colorado. But stay away from Dart 2.6. I got this bike in end april bewildered by its looks. But its performance and ride qualiity was so poor. Starting from compnent failures like disc brakes, improper gear shifts and squeeky noises and worst tyres prone for punctures. I was having a tough time.
I have upgraded to Shwinn Sporterra sport and the change is remarkable. If your budget constraint look for Rock rider which i see has beautiful reviews in Bikeszone. Check Bikeszone fourms before concluding a buy.
Better to get a Hero/Hercules Roadster commuter than these junk yards.....Go Rockrider or other imp.(except Trek3500).theres few used bike sale news in FB, can try them also.
