The Ebay car LOOK real nice. The V.I.N. is wrong as the plant designation show a plant that did not build Roadrunners. Could be a typo, could be it was input wrong at the DMV for the title, but it should NOT read that way on the V.I.N. tag. First thing that should be confirmed.
Not much info about what a lot of people find important when looking at these cars. No mention of a fender tag, broadcast sheet, or hidden numbers and confirmation of these things.
More importantly I would want to see some info as to where the car spent most of it's life, if it had rust previously and if so how it was repaired and with what. That would just be a start for me.
The other car showing just the one picture and no other info doesn't give much to go on. As for the laquer paint and it being 10 years old, that is quite unusual. It has been illegal to spray it in most states for a long time. It is great paint for easy touch up and blending but typically cracks with hairline crack with age especially in high temp. climites. It is a very thin paint and will show EVERY imperfection under it so the body has to very straight before paint. It was used by GM back in the day but Mopar used acrylic enamal.
