Are you asking whether we think they are worth the money?
The average well appointed 5spd hardtop GT will set you back about $24,000. Whether or not it's worth it to you is dependant on a bunch of different details. Can you fix your cars yourself? Do you want a warranty? If you have a warranty, will you wind up voiding it anyway?
That one is particularily interesting food for thought.
I think they look awesome, they are damn good in stock form, they respond to some pretty simple mods like gears quite well, and they respond for forced induction very well.
I don't think I would buy one over a '99 DOHC Cobra, but it's all up to you. The cars are worth whatever you are willing to pay for them.
Are they a good car? I think so, I love them.
