Advice on buying used GEM

We are looking to move on from our golf cart, and purchased a GEM car. Found one that is not currently working. The man who fixes our golf cart said Gems are fun, but a pains and expensive to fix. We are guessing this GEM will need a new motor. Would love any advice.

It would help greatly if you provided details on what you bought.
Do NOT say it is a 00 - 04 car.
Why do you feel it would need a new motor?

Always bet on Black.
Buy stock in DMC. It is a small startup car company that will be HUGE!!!

Pretty broad brush he’s painting with there.

Based on what / whose diagnosis? Dr Doom the mechanic?
