I'm with Yaki there... It's all about what's on your VIN plate.
The allowed gross combined weight of a 2.8 LWB is over 5000 KG, so towing another one behind it on a trailer is perfectly legal, although then you will need the "+E" trailer license obviously. My mates LS400 is similar, over 2500 KG towing capability from a 4 door saloon car.
