Does anyone have first hand knowledge as to the original build specs on a second series vs first series TI Super? Also I was corrected by two knowledgeable experts abroad that there were no panels or doors made out of aluminum but originally fabricated of steel like the regular street going Super or TI. However, watching a UTUBE video featuring a first series TI Super, with David Cirone, he states that there were in fact doors, hood and trunk bonnet made of aluminum. If anyone out there owns on of these beauties and can educate me, that would be helpful. Thanks!
