New car needed

Are you miss reading? The picture seems to show 1650kg braked which would be fine for a 1485 MTPLM?

It's the kerb weight that is confusing me, at 1425kg it would be 104% and that is not ideal or wanted.

The kerb weight is the worrying part.  At 1425 it would be 194% with the van, not ideal or wanted.

Call the kerb weight 1500 for the sake of simplicity. Your van is 1485, whereas 85% is around 1275. It's not illegal but I'd not want to tow with that set up☹

I would expect Kerb weight will be around 1500 without any payload. Add a couple of passengers a tow bar, a. an awning and other associated gear, the gross weight of the tow vehicle will be well above 1485. 

It's the kerb weight that is taken as the guidance for safe towing and, if you adhere to that 85% theory, this is not a good match. If you don't bother about that guidance, then all is fine. 

The legal bits not to be exceeded are the gross vehicle weight of 2050, the gross train weight of 3700 and the max towing weight of 1650. Keep within thise weights and it's legal although, to my mind, the rig is far from ideal.

My only concern would be if towing a fully laden van with an empty car, but would that ever happen?

Is the VW Tiguan on the scheme as it might be a bit heavier and is a good every day solo vehicle.

Thanks for the replies.

Tiquan like many others is not available, Kuga is not available in anything other than petrol electric.  Seems most if not all diesels are gone.  Skoda superb might be an option but upfront costs are now 3 times what they were.

Can you keep the one you have?
