The '99s did have an intercooler problem and yes, they were recalled. If you find one that interests you, pull the VIN and have your local Ford dealer check their database to see if the previous owner had the recall repairs made.

As for options........ Lightnings come well equipped and the only option I've ever know them to have is the factory soft tonneau cover. The '99 models did not have an overhead console and I think they also lacked the side mirrors with the built in turn signals.

Good luck!
