Is it worth the bother to remove tow plates?

On the other side,I was looking for a car to buy for a toad and found a great low mileage '06 absolutely loaded Liberty. It was 6 years old and only had 40K on it.It was a bit overpriced,but absolutely awesome.As I was looking at it,I saw it had the tow plates on it and a light harness. I asked the salesman, a guy I had known for years, how many towing miles it had on it and he was surprised that I knew what a toad was. He said he didn't know as someone else had done the trade-in on it.I asked if he could find out and also why the whole front end had been repainted,you could see the overspray.I went back the next day and he told me that it had over 70k towing miles and that the previous owner had taken it to Alaska and hit a bunch of loose gravel and severly dinged the front end. the car was up for $14K,which was seriously over book and I offered him $9500 and he grinned and took it to the boss,who laughed at me. Naw,I didn't take the counter and left. The guy told me later that they had removed all signs of it having been towed and got the $14K for it as it was a gorgeous low mileage Liberty.
