You are going to run into quite a few issues:
VERY FEW lender's will touch an open Chapter 7, in addition those that do specialize in open Ch7 Auto lending are going to have an issue with your income because I would think you are a 1099 employee through the ride share companies. In which case most will want a tax return to prove income, if you have filed taxes on your income in the past. They will look at your 1040 schedule C, typically line 31 to calculate your income. Other lender's will use 3 to 6 month's of bank statement's to calculate income, where they will take your deposits and add them together then divide by number of month's of bank statements to calculate monthly income.
Another huge issue you will run into, is the fact that your vehicle is being used for ride share services. Most all indirect lender's (indirect lender's are lender's that dealership's use) will absolutely not finance a vehicle that is going to be used for ride share services as it results in faster depreciation of their collateral.
In addition, unless you have terrific credit history pre BK filing and you are placed in a high tier, most likely you will need at the very least $1,000 cash or equity down, or 10% of the sales price depending on the bank/and tiering.
CPS (consumer portfolio services) is a lender who will finance someone in an open Ch7 provided you have had your meeting with creditor's already, and they will finance 1099 employee's with documentation as stated above, but they will not finance vehicles intended for ride share services.
My advice: Buy a car for cash to get you by until you are discharged from your bankruptcy, and able to rebuild your credit to get a better approval (less money down, lower APR, etc) and find a different job that isn't so reliant on your vehicle situation. Once you are in a better spot, then start doing ride shares on the side again or start doing that full time once you've obtained a decent vehicle and established an emergency fund.
One last note, I would also look at a more practical car if your doing ride share services, a nice 2013+ Honda civic/accord with decently low miles would be a much better fit for that type of work.
Good luck.
