Is this Duster overpriced?

I can't help but notice a few things. One, he didn't send you pics of the VIN tag on the dash. Two, the condition of the Data plate and inner fender well don't match the outside of the car.
I can't help but think this is a cheap repaint car, that if you ask for pics of the underside of the car are going to show some very serious signs of it's age and need of repair, which will be expensive if you can't do yourself.
I had a duster with those same shackles, went through u-joints about once a month, until I replaced them with stock ones.
If I was serious about wanting this car, I would certainly ask for more pics and see if a FABO member close could inspect for you.. They will tell you upfront what the car may or may not need. Pics can and do cover some mighty shody repair work.
