We all tow for a small percentage of the time.
The volvo was not very user friendly, the auto box was slow and old, the gps system was too fiddly. The electric boot was too slow to open, the oil level increases as diesel seeps through into the sump, you cant check the oil level easily as its electronic that nobody understands. The button to release the damn electric boot is next to the filler cap button, so you pull up at the petrol station and the boot opens and the dog goes awol. The aux belt tensioner fails ( volvo know about this). The merc is a far better engineered car.
