Adding another credit card (secure) that will help lower my credit card balances?

 I used the Postmates app currently. I have done Uber and Lyft in the past. Because I watch my father Postmates works out better.  I can use a scooter but I used Lime once to get back to the house from the bus stop, after I dropped off the car I was using back to where I got it. 

 For a little more than 2.5 miles it cost me $8. I've seen some people do Postmates on electric scooters but it's not cost effective IMHO. 

  I haven't even had $500 free at any one time. Of course I could leverage time and earn before some bill was due. But the only cars I would consider for about $500 fees included would be an auction car. That said anything I wanted was back east, which would mean airline flight as I can't spend the time taking the bus and the train is actually more expensive over great distances. Plus fuel and leaving some money available in-case I had to make a repair on the way back.

There have been a couple of Pontiac Grand Prix GTP's for $375 without bidding plus fees. These were reposessions, run and drive, very little damage. 

 One car like that is coming up for sale but that won't be until March 11th. Another car has not been cleared by the debt holder yet.

 Sort of....

 I understand the risk of doing it that way. But from my perspective I think it makes sense for a couple of reasons.

 1) Using cards means it's easy to purchase and pay fees on auction cars. Many companies like IAAI and Copart are going exclusively to online bidding on vehicles. If I was paying a broker, for the car and all the fees to complete the transaction I can used one card for that.

 How is paying 25% on cash advance some how bad vs dealing with Carvana's 26-27% interest on a car under $9,000 TTL?  Especially with Carvana/CarMax/DriveTime jacked up prices, no negotiating and generally bland choices. 

 2) I avoid spending cash to buy private party vehicles. Private parties barely take Paypal let alone credit or debt cards. I have a line on a car around the corner from my house. I would make my final offer but I don't have access to the cash and because it needs repairing it's not going anywhere since the turbo version of the car is more popular than the supercharged version, I'll give you a cookie if you can guess what model it is.

 The goal is to buy that car at the lowest price possible. Estimated repair cost to make it reliable again is about $1,000. To fix everything that's wrong with it, is another $800-$1,000. NADA retail value for a car with the same mileage is $3600. Even with that investment I would save $600 and the car would be back to showroom condition.

 Since the first of the year I have reduced my exposure. Cost is right around $120 a week/$480 a month. That is nearly $500 back in my pocket not including fuel cost because I have been using a hybrid as much as I can. I would spend more with the cars I typically own but not dramatically so.

  I can be aggressive paying the cards back down with expenses reduced back to normal levels.
