What would be a good first car?

I still have a year until I get my license but I'm trying to plan ahead of time so when I know, I can get a car and know what I want. First thing, I do not like small 4-Cylinder cars… Here in michigan people drive really fast and the highways are very hilly. With 4-cylinders your foot is ALWAYS planted and it's not enough. I don't really know what would be a good first car… My price range is about $18k at the most. I found a lot of used 2008+ Ford Flex (leather and all that) with around 75k-120k miles for about $14k-17k. Would that be worth it? Tbh I really don't even care if it's a minivan, as long as it has a V6 and isn't a small tiny car, I really don't care. Please don't be rude! Any suggestions?

1998 Ford escort zx2 running sluggish?

Thanks for taking the time out to read my post. I bought this car about 6 months ago it has 150k on it. When i bought it the owner who is a friend, he showed me all the work he put into it he replaced the timing chain and put a new gas tank and flex pipe.

he told me that the car would stall every now and then but would start right back up and work fine after that during the 6 months the car never backfired didn't have any misfires ran fine. Until one day i felt a hesitation that led to a stall so like my friend said it started right back up and seemed to run fine. Later that day the car was running sluggish / hesitating / misfiring / loss of power.

there was a check engine light that came on I checked it and said my co2 sensors where bad. So i decided to give the car a complete tune up I changed the spark plugs wires coil pack air filter both 02 sensors fuel filter fuel sensor.

after i did all that the car ran fine for about an hr then it was just simply hesitating with a slight misfire so I checked everything to make sure i didn't leave anything loose and everything seemed to be fine. But still hesitating with a low idle so I thought it might be my fuel pump so I changed it with a rebuilt one. After that it ran fine for a few days.

it started again but now if i take a hard turn the car will stall and die so then I changed all the fuses and relays that helped but didn't fix the problem I was told maybe a mass air flow sensor or a throttle positioning sensor?

Does anyone have experience with this automotive industry position?

I have an interview set up in a week for this position with a local auto dealership. Below I have posted the job posting. I'm trying to get an idea/gameplan of what to expect. The recruite was very broad on the phone. Does anyone have any experience with this? What does it sound like to you? Does it sound like a car salesman position?

My credit score is 523, which is very poor. I have saved $8000 and want to buy a new car and finance $15,000

As stated, I know my credit score is 523 from TransUnion and Equifax shows it at 525.

I have $8000 in cash, plus a car to trade worth appx $3000. The used vehicle I want to buy is $23,000. Will I be able to finance the balance, even though my credit is terrible?

If it matters, I'm purchasing wither a Ford Flex or a Chevrolet Equinox, both used, low miles, in great shape, etc… I'm unsure if GMAC or Ford credit would work with me? The only positive on my credit is the same job for 17 years, and I make a little over $1000 a week, own my home outright so no house payment. MOST of my bad credit is very late medical bills, but I also have 2 apartment evictions back in 2008 and 2009. I have no active / positive credit.

How to troubleshoot engine vibration?

I have a 1998 Ford Mustang, 3.8l. I swapped the motor for the same 3.8l. Everything is all buttoned up. The motor starts and runs. Its idles normal in park and in neutral. Once it is put into any gear, the motor shakes a bit, has a low idle, and a severe loss of power. Taking the car on the street is not an option because of the lack of power. Almost like a major vacuum leak. I checked and replaced all vacuum lines, new plugs and wires, new mass airflow sensor, all fluids are full, fan turns on and thermostat is working great, no leaks. OBD2 with no check engine light. Can't seem to figure out what is causing this issue. I was thinking the harmonic balancer, but can't seem to find anything wrong with it. Any suggestions as to what I should check next?

Added (1). I used the o2 sensors from the old motor, the harness from the new motor. I used the old throttle body, iac, altenator, battery, and pulleys. The car is running rich, the exhaust fumes are too much to bare while the car is running in the garage with the door opened fully. I had one check engine light, mass air flow sensor, replaced it, and the light was gone. I hooked the scanner up again and there were no codes stored. I ran the diagnostics and found my o2 sensors running at 0.00

Added (2). Also, I used the old trans, torque converter and flexplate from the old motor
