Have had four cars which I put  towing bars on and nothing was said by buyers when selling . What is  your opinion.

I bought a toyota land cruiser that had towed a big caravan all round europe it had covered 160 k odd  miles when I got it, It had been  

meticulously maintained. I have had it 7 years and has cost no money other than normal service costs. Great buy. A lot of people fit tow bars to carry bikes etc as well I wouldn't be put off by a tow bar.
