What does the word " reconstructed " mean on a Pennsylvania car title?

It means the car was determined to be a total loss.

Someone bought it, and put it back together using parts from at least one different vehicle.

Most states call that a "salvage" title.

You will have a hard time getting full coverage insurance on that vehicle, and you should not have paid more than half of the value of the same vehicle that has never been totaled.

It means it was a salvaged vehicle, which was completely rebuilt to be road ready

Salvage Vehicle

Essentially, this type of vehicle is one step from the scrap heap. A vehicle in this condition earns the tag "total loss" by an insurance company for any one of a slew of reasons like wrecked beyond repair or flood damage. Yet, thanks to a bit of grease monkey ingenuity, these crunched and junked bits of mangled metal make it back onto the road. Some of these salvage vehicles run as well as they did when they first came off the assembly line. Regardless, if an insurance company totals a vehicle, in order to maintain possession, the owner must apply for a salvage title.

Rebuilt/Rebuildable/Reconstructed

This branded title signifies a salvage vehicle that is usually ready to take to the road. The vehicle has typically undergone a complete rebuilding with new or used parts. Each part is recorded, and the entire rebuilding process is documented by affidavit.
