I'm looking for a word for the following things (they may be the same, or have different words):
- cheap car modified or constructed by owner using scrapyard and low-end tools (and thus having certain "quality")
- cheap car with expensive and redundant modifications (golden bumpers?)
- a regular car which has almost all parts removed and/or replaced to make it more lightweight and faster up to make it unusable for everyday use
- not a car but technically complex thing fits any description above
The only words I've found are junker and jalopy, but may be there is more?
EDIT: Commenters asked me to present a sample sentence, but unfortunately I'm trying to find a name for a blog, so there is no sample sentence. May be "%word% Lab" or something.
