I drove with four people in my XK8 coupe today.
Here is a picture I took with the door open.
Next time I will pick up Lieutenant Dan.

One adult and two kids works great.
Two adults and two kids not so much.

Next time we will take the XJS.

 

Ha! Depending on how old the kids are, it may or may not work out. Ours are now 6 and 3, so they fit back there for the time being. I believe the rear seat room in the coupe is not too far off from the convertible?

 

The coupe actually has more space in the back. But my kids are 11 and 7 and everone in my family is German size. They fit in the XJS just fine.

 

I had two of my grandkids in the back once. They were little and I'm 5'7". I was on top of the steering wheel.

 

Wait a minute, those look like dolls in the back seat. That can't be real.
