		Lew, 
You really should visit Kirkham Motorsports and see the 427 and 289 FIA cars.  David and Tom usually have several cars in various build stages as well as their own personal cars you can look at.  They are world class people as well. 
 
The transverse leaf 289 car rides a little different than the 427 or coil sprung 289 FIA hybrid, not quite as refined.  It depends if you want authenticity, track handling, ride quality, etc. 
 
I have my opinion on which car to buy, you'll have yours.  Bottom line...you should go see the cars, see the facilities, and meet the people of all Cobra manufacturers you are considering.
