My dad has a '71 E-type 4.2 Series II. It looks absolutely absurd in modern parking spaces parked next to modern cars, like a toy because of how small it is. It also makes the current gen XK8 parked next to it in the garage look like a fat whale.
Your dad has taste. I congratulate you with an E-Type in the family.
Years ago I had a V12 XJ-S that was fun at the time, but had endless eletrical issues.
