i myself am probably the biggest SALEEN fan in the world, at least until they brought out this new body style. for personal reasons, i would still pick a Saleen. ok, now with the problems. i have had a chance more than once to "carefully" inspect both cars, and i have to be honest, the Saleen has issues. at least to me it does. if you inspect closely, you will notice the body kit don't line up correctly, the gaps can be terrible. to me, if paying $40K plus for ANY car, it better be perfect! the interior is not all that great either. the stitching looks crooked, and the leather doesn't look like it was pulled tight. again, this is just my opinion, and my findings. i haven't personally seen anything wrong with the Roush line, but the one thing i don't like is a stick on bumper extension, and that's what you get with a Roush, so they both have issues to me. but my choice would be the Saleen. personally, if you can find a dealer that will sell you a GT500 for sticker, i would go that route instead of either...
