old guy needs fun modern-ish driver

I have been looking at late model Stang ads. On FB Marketplace, you see a car and price. Little to no info. On the FB Stang groups, cars for sale usually have lots of info. I figure in general the difference between honest hobby type sellers and whatever Seems 99 of them have had "tuner" stuff and parts added out the ***. Maybea car advertisd at say $9000 that had $10,000 worth of mods is a good deal! ha You seldom see an adult unmodified car.
I see lots of Stangs that have had a new engine added at just over 100,000 mi. Talking of v8 cars. Not good. Abuse? Probably.
I see Stangs where the maybe "young" owner tried, for example, a cam swap etc, and had major issues. I see a lot of young guys dong mods with no mechanical clue. Hum!!???
