Upgrading from Nuevo

We presently have a Nuevo ES and are thinking of upgrading sometime in the next few years.
Because of our driveway limit we do not want anything much longer than the Nuevo, could manage at best another metre and staying with coachbuilt 2+2.
In so doing we were thinking of securing towing ability of a car up to the size of a VW Golf, A Frame being preferable. Idea is our daughter having the car and us using it to tow when off and away and she using our, larger, car during these periods. Our daughter is likely to be replacing her present car shortly so want to steer towards something suitable for our needs. She would prefer something the size of a Golf although a Fiat 500 has also been mentioned.
So ideas regarding A/S models to consider and size (weight?) limitations on type of car that could be towed would be most helpful.
