Considering an electric car retrofit kinda project. Need guidance or someone to tell me don't do it.

The electric E30 is still on FBM, now priced at $5k.

Someone on DIY Electric Car was asking about the Spark EV as a donor for a 2nd gen DSM conversion.

1) They seemed to be thinking about using the Spark motor with the DSM trans, like you would do with a Leaf's EM61 or EM57 motor.  Technically the Spark's motor will unbolt from the rest of the drive unit, but the motor is NOT nicely sealed and self-contained.  The output end of the Spark motor does have a bearing support (I think Teslas do not even have that), but otherwise it is open and the coolant pump is in the 'gearbox' half.  Fun factoid: the drive unit is a "1ET35", GM applied their transmission naming convention as a single speed transverse.

2) Supposedly the 2014 Spark EV had a 3.17:1 "final drive" and the 2015 had 3.87:1.  Either way, there is only one stage of planetary reduction so the Spark uses a low "KV" motor (low RPM per volt applied, equiv to a high turn count R/C motor).  As we all know from this thread, it normally does not work to create a mid-engine AWD car by taking a FWD engine+transaxle, turning it 90deg, and connecting the halfshafts to front and rear diffs (double final drive reduction = sub-60mph top speed even with really tall tires).  HOWEVER, it might actually work with the Spark drive unit if you weld up the planetary.  Of course, it may be simpler/easier to use separate front and rear drive units rather than a single motor and mechanical AWD.

The electric E30 sold some time ago.  However I found something else for y'all.
IDK if it qualifies as 'you need this'...

1982 Ford Esc0rt, old skool EV conversion (96V, brushed DC motor, set up for lead-acid).  Free to a good home.  (Batteries not included.)

First posted in 2021, but still available.  Presumably in Colorado somewhere, I'm not sure where exactly.  I could volunteer to look at the thing if it is local-ish, maybe even store it for you for a very limited amount of time.

Personally I'm sorta tempted, but just not enough even for 'free'.  I might be able to pull off 'simply' putting in batteries.  The big problem is that I'm not like passionately enthusiastic about the Esc0rt, and that is a really bad omen.  My grandparents had a beige 4-door long ago but I never drove it and I don't have any first hand nostalgia.
Really, the major problem is the conversion is too nice.  I want some f'd up worthless POS so it won't matter if I completely butcher and/or never finish the thing.  I want the correct parts to be either cheap and easy to get, or to be absolutely unobtainable so hacking and adapting is the only option.

I grabbed this about a year and a half ago [[relative to Aug 2021]]. Replaced all batteries, tires, sear covers, various lights, repaired vacuum for brakes, replaced brakes, and some other various things.
Have driven weekly around town, and for running errands. Fun little car.
Registered as electric in Colorado and have enjoyed the time I’ve had it. My work is now a bit farther than I can use this for. I’ve taken it 30 or so miles but not farther. I have never tried to max it out. If I kept it I was going to update from the 96 volts currently powering it.
Runs and drives with the factory transmission. This was originally a college project and I have all the books and manuals that came with it.
There’s a little rust on the lower corner of the back deck and a small spot at the top in the rear. Looks great and people always ask about it when I take it to town. It isn’t something you see every day.
Motor: Advanced DC 203-06-4001 Series Wound DC

Drivetrain: 4 speed manual with clutch

Controller: Curtis PMC 1231C-7701

Batteries: 16 US Battery U-2200, 6.00 Volt, Lead-Acid, Flooded
Installed new about a year and half ago. 4 under the hood, 4 under the rear seat, 8 in the rear battery box. The two interior battery boxes are metal, sealed and vented. During charging, a fan vents the battery boxes.

System Voltage: 96 Volts

Charger: K and W BC-20
At empty, it takes 12 hours to charge at 12 amps DC charge rate (18 amps AC 120 volts). In can use a 30 amp 120 volt plug for faster charging.

Just an idea that showed up on Marketplace

Edit: Batteries supplied by CanEV looks like 3.2V 206 A  23 kw 36 @ $C326 = $C11,736
