The Esteem was a family owned car (co-owner's, wife's Grandma, then the young niece that was her caretaker) and appears to have been well maintained....but...
It was and is rusty. Caged with no issue except Jeff Glenn mentioned a couple of the less than perfect spreader plate to sheetmetal welds because of the thin sheetmetal. We can likely correct those but because we are "known good team" they let us race. Full compliant fire system with a date of about March 1, 2019. Forget the date on the belts. Rear subframe mounts have signs of rust but if you don't disturb them, likely fine.
It is a 1.6 Auto which means it is a 1.6 auto (Suzuki engine, 4-speed tranny from Nissan built under license and not terrible). Mazda BP 1.8 was the other motor with a Mazda 5-speed available...just sayin. No clue on rear disc conversion but honestly, we hardly needed brakes. Mazda NA and NB wheels fit it if you clean the center bore by about 1.5 mm and they have correct offset.
Seat is on a slider that rides up so should fit about 6'2" to 5'4" drivers. I do not plan to include the seat but if you want it, it is a Corbeau FX1.
Only real issue is we could only put about 7 gallons of fuel in it before a fuel leak. The filler neck was rusted but repaired (we thought) and the tank had about 70, 000 fittings on a rusted steel barbs most of which we blocked off leaving only one vent to the filler neck.. Yours to troubleshoot.
I can do a total but about $800 for the cage, $440 for the fire system, belts are only like $100. Lets call it $1300'ish (no seat) and I still have to get approval from the co-owner.
Esteem was known for exceptional handling in its day but until we let one driver go nuts when things finally dried out, it burned less than 4 gallons an hour. Even in the rain, braking was optional. Built in "Low self Esteem" theme since we already did the "Better Call Saul" theme.
