I saw a 2001 Plymouth Neon for sale on the side of the road for $700. Stopped and looked at it. Body and interior in good shape. Manual tranny. 338k miles--ouch! Talked to the owner. She says it is more highway miles. Started it up--no problem. Sounded good. Looked under the hood-looked to be in good shape. Clutch seemed 'loose'. Owner said they just installed a new clutch--it's a 'racing' clutch. Check engine light came on when I started it--stayed on a minute or two then went off but came back on a few minutes later. The owner said she took it to a parts store and they told her it was a 'sensor'. She said they bought it new--it does have a local dealer's sticker on the back. Thoughts??
