Long list in my head but I'll just list a few here.
* BLACK engine bay in ANY Mopar that is not painted black on the exterior.
* The core support with NO blackout on every car that isn't black. A guy restores a car and fails to paint the support black, so now you see the body color on the other side of the grille.
* Wrinkles in headliner or upholstery.
* Universal corrugated radiator hoses.
* Corrugated plastic wire loom on the factory wiring.
* Plum Crazy, Sublime and other 1970 and later colors on a 1969 or earlier car.
* Aftermarket gauges stuck under the dash instead of fixing the factory gauges.
* Inconsistent body panel gaps.
* Chevrolet style Cowl hood scoops.
* Back end of the car jacked way up with N-50-15 tires sitting out past the body.
* Those show car posters on an easel with incorrect terms, misspellings and false information. No Mopar ever had a Posi or a Police interceptor engine.
That is all until I come up with more.
