83 XR7......Why do I have a P92 in a LS trim? February 03, 2019, 05:18:20 PM Have this really weird car. The car is marked LS. With a 5.0 which I thought XR was only turbo?Found it in harrisburg Pa with 65000 miles in MINT condition for $1000 bucks. Everything seems weird. Did a car Fax Pebble beach Ca was delivered. Stayed under 10000miles until 1992. In the trunk I found a Pen from the . I thought all 83 California cars were the 3.8 due to lack of 5.0 used up in the Tbirds and mustangs. Also thought there was no xr7 for 83. What is this car? Heard it may have been a Factory Demostrator or Promotional vehicle. I dunno also has a weird 1/4 vinyl roof I’ve never seen before.
