You want to know if you can fit a towbar to tow a trailer or caravan?

Yes, this is fine.

You should check that the car is OK to pull the size and weight of your trailer.

You can get the cost included in the car deal, or you can fit a towbar after delivery.

Having it fitted yourself means that at the end of the contract, you can take it off and stick it on eBay, to get some money back.
