I don't know Gramps, going from 3 spark plugs to 12.....that's quite a leap. Are you sure you can handle it? I mean ya did say, "pushing the clutch 5 times an hour requires heavy doses of oxygen".
All kidding aside, you can't find a better car for the money. And you're not going to find a friendlier forum to move into.
I love my coupe, but if I lived in Calif. I'd probably have to add a XF roadster as well.
Good hunting, and welcome.
