If the VX is in otherwise good shape, I would use the spray painted cladding and wheels as a bargining point. Then buy it, ditch the wheels for some aftermarket rims that are nicer and cooler looking, and then just take your time cleaning the cladding. It will be some work, but can be done I would think.
Go rescue this VX!

PS - When a person spray paints a vehicle, they MUST know that they are making a conscious decision to commit to the vehicle, most likely forever.
