Long time since I'd seen an Espada! Quite the lineup.
Any of the "exotic" examples we'd get in the shop for resto or engine rebuild, after I'd done the engine I would drive it the first five hundred miles to be certain it was right. A come-back due to immediate client abuse was not an option. The "responsibility factor" was always first and foremost on my mind. A Weber'd up V-12 Ferrari 400 was the last one I did, drove it as a commuter car for a week. 100 mile round trips to home and back, mostly on an Interstate highway. Had "cr*p down th' back of me neck" most of the time!
I'll stick with my humble little four cylinder examples, thankewverymuch.
