In reply to Woody:
Eh, it's quite possible that my Ma just passed along whatever the sales guy said to her. Ever wonder who bought those 4-cyl 3rd gen GM F-Bodies back in the '80? My mom did. Sales guy told her it was a V6.
I tried to get her to take it back after I saw the ol' Iron Duke under the hood, but she didn't want to make a fuss (Old School Southern woman..). We eventually started calling it the "CAFE Racer".

The CRX replaced the Camaro, she had an Olds Alero after that, and now she's in an '08 or so Mitsu Galant.
EDIT: Normally I'd apologize for the thread tangent, but I'm just so jealous you found that car.
