Must agree, John, on all comments. The original box section frame is prone to a number of failures, both from stress and corrosion. Both of my cars are currently inoperable due to frame damage from these problems. S3 has cracked across the lower "shelf" due to differential stresses and the +2 suffered collapse of the right front upright from DPO neglect of the drain holes... and I've seen many other Elan frames fail at other points. Spyder has an elegant solution, unfortunately it just is not in my budget for the time being. If it were otherwise, I wouldn't hesitate to replace the originals with Spyder units.
