Can you have such a thing as a dream towcar? I can see a dream car; I can see a towcar. I'm not at all sure they could be one and the same vehicle, for me at least
Towcar is a BMW X5 E53 3.0d and excellent it is too (don't see many towing though). I could not see any reason to change this, and certainly not for anything that is funeral black inside and out. If I weren't towing, would I buy an X5 as an everyday car, probably not, nor indeed any other 4x4, so I couldn't class it as a dream car.
Not necessarily a dream car, my BMW 750iL from 1999 and seven years older has a far better ambience in which to travel and is also a slightly better towcar - it just has a bit of a drink problem when towing, and Red Pennant annoying charges more for vehicles over 10 years old. But this is the one I would choose to travel in
