I have seen three seals recently. Just found a tow bar option for my MG4 Its a 500KG or 750kg braked I think. I want one for my bike rack.
 Tow is far to light for my boat. 
The Seal is rated to 1500kg-1750? towing.
My D3 power was 
140kW of power at 4000rpm and 445Nm of torque at a low 1900rpm
Seal mid options is 
- Maximum Power - 230 kW
- Maximum Torque - 360 Nm
It isnt a off road beast of course. It could now tow my boat I assume up to about 300km which is interesting! It's range claims of 
- Up to 650km range NEDC - 570km WLTP
I may be fishing again sooner than I thought[thumbsupbig] Add Diving from the boat is so much safer than scampering over the rocks as I have been doing recently.
I am going for a test drive tomorrow!
