Went & evaluated the 1991 745 I found - it had been picked at - fortunately not too much missing under the hood - brake booster hose & valve, alternator mounts, injection relays....
Regina-Rex NA
little extra something over here
interior is good enough - manual seats, manual mirrors, manual sunroof, no cruise
Exterior is pretty decent - in terms of lack of damage - will need paint or course when it's all done. Roof is really the only place where the paint is actually gone, and that will be cut off anyway. Not too much rust underneath, a few spots but nothing I can't deal with fairly easily.
nice patina over much of the car...
I needed to hear it run before I said yes, even for a $500 buy - especially since it's Regina-Rex.
Hooked up a booster, checked the fluids & cranked. Nada - that's when I found the missing injection relays - still no start - couldn't hear the pump(s) - so I checked the CEU - someone swiped the system relay "E"...
After I located a used relay, it cranked a little & fired right up - idle stuck around 1500 - that's when I found the brake booster hose missing. Checked the trans goes into each gear. Power steering pressure line has rotted at the rack fitting - I added a quart or fluid & it pumped right out.
Car will need all the suspension refresh & brakes eventually - rotors & calipers are rotted away. It's been sitting on this lot for a couple years.
Quick check of electrical systems - power locks work, antenna works (lol), flashers & lights all work. So, I feel OK about using this as the starting point.
