new owner 2005 Prius questions

I need some advice so bear with me on this rather long story. I recently bought a 2005 Prius with 128,000 miles for cheap, around-town transportation. I bought off a private seller. So far, the vehicle is performing excellently--drives perfectly (wife just returned from a 100-mile trip to Nashville and fell in love with the machine), averaging 43 mpg. Good paint. Nice interior. Before buying, I pulled a Carfax which showed that the first owner had a Toyota dealer perform regular scheduled service. No wrecks reported. The original owner, now aged 85, sold the 2005 to a neighbor at the end of 2016. After that, no more listings on the Carfax. The guy who I bought it from explained that his brother serviced the vehicle. He had installed a new hybrid battery as well as a new 12v because the first owner let it sit for more than a year (after his wife died), which killed the batteries. The batteries looked new, but what do I know since I have no experience with Prii. I'm learning fast, thanks to Priuschat and U-tube videos. One of the videos I watch showed the changes from a 2005 to a 2006. One of the big differences was the dash board. The 2005 has a smooth painted dash while the 2006 is covered in a textured material. Today, while sitting at a traffic light, I noticed that most of my dash had a smooth black surface. However, the glove box and the steering wheel had a textured surface. Finally my question, do any other 2004-2005 owners have dashes with textured glove boxes and steering wheels? As I see it, my dash indicated that the frontal air bags were triggered by a wreck which was not reported on Carfax. Another possible explanation is the dash was replaced during an air bag recall. Any opinions, speculation or knowledge of this situation would be appreciated.

 

Thanks. I'm leaning towards my wreck theory and wondering what else the seller failed to disclose. I had the car checked by a mechanic who found no problems, only that the rubber shock covers were beginning to deteriorate. Next step is to have the "new" battery checked.

 

Have asked seller for sales slip for the HV battery but he has not responded to my calls. So I'll follow your advice on finding the date code. I do know that the battery is not an official Toyota replacement battery but was bought from a battery rebuilder in the Knoxville, TN area.
