Those CMX wheels were an oppition on these cars! Mine did not have the sun roof or wheels, also had a 79 5th and 80 Mirada CMX Ttop years ago, Wish I could have this one!
Often those wheels were a part of the "open road" package (aka cop suspension). I can't say for sure if this one has it, but it looks like the 9-y/o optioned it. I probably got distracted by a Dukes of Hazzard episode and missed the E-58 360 (still available in '81?)
For the record, if it had that engine I'd never consider an engine swap.
