It's a standard part and extremely easy to fit. It's a lightweight tow bar with a limited weight capacity, but it works fine with the 8-foot utility trailer I use to haul gardening supplies in lieu of a truck. You can haul up to a ton with it and stay in specs. I wouldn't take it on the Interstate, but it's fine between the house and the garden center. https://www.suspensionconnection.com...caAizREALw_wcB

 

The tow hitch you can buy in the US for an XK8 (which attaches to pre-threaded holes) is rated up to 2,000 pounds tow weight, so I wouldn't think there'd be any problem doing this at all as long as you kept the speed reasonable.

 

Let's see ... I've put hitches on:

1968 VW Beetle (m/cycle trailer short distances)
Camaro IROC (family boat)
Camaro Z28 (family boat)
Mazda Miata (m/cycle trailer)
'84 Cadillac Elderado (family boat)
2005 Corvette Z51 (light weight trailer for racing tires)
2007 Corvette Z06 (light weight trailer for racing tires)
2018 Lincoln Continental (jet skis)
... and a couple more I can't remember

Just be careful about weight and not over-strain the drivetrain, suspension and brakes and drive at moderate speeds. It'll be fine.
