If I were you I would pass on both televisions.
The Thomson Model number you gave me indicates it is a CRT Rear Projection, probably from 2004. Now CRT rear projection can be excellent to those who appreciate its video qualities (does not produce eye fatigue, excellent blacks, color depth, and potential color accuracy), but RCA (or Thomson) was not, from my understanding, noted for their CRT RPTVs. Their DLPs rated somewhat better. In CRT RPTVs, Mitsubishi, Pioneer, Hitachi, Panasonic and Sony rank higher. It all depends on model number.
The Pioneer model you mentioned (also CRT RPTV) is even older, probably manufactured in 1997.
I can't imagine that the Thomson CRT RPTV is all that reliable, or easy to repair, and there's a lot that can go wrong, even if the CRTs themselves may be long-lived.
Once again, your friend (who you might consider demoting to acquaintance) was being less than candid with you about the television's age, based on the model number you gave me.
I would take your time to look for something newer and more reliable. RPTVs are not that popular right now, and you should be able to find an excellent one at a good price if you are patient.
At least you have a great car!
