What vehicle would be best for me?

I'm 20 years old and in need of a new car. I'm looking at 4 models of 2017: Kia Rio, Chevy Sonic, Honda Fit, and Ford Fiesta.
I'm looking at something with longevity, great MPG, and few problems, and won't break my bank account if it needs work.
I have them ranked in my mind from best to okay for me but would like advice.

Ford 2002 speedo and rev counter starts at -20Mph/-2000rpm?

I Have a 2002 Ford fiesta bought at auction, the speedo and rev counter are zeroed at about -20mph so when you are doing 50 it appears as if you are doing 30, replaced the clocks. Before programming new IC i self tested the IC and revs and speed acted as they should but when i programmed the IC to the car the revs and speed reverted to the -20/-2000 position. I put the OBDii software in live view and the speed and revs outputted by the PCM were displayed correctly (iding at about 1100 rpm) but IC still showed -1000ish. Getting error codes u2200-63 and u2197-63. What would be the likely cause?

Added (1). I'm just looking for the most reliable car. Oh and if any of them have in-built bluethooth that would be nice. If there's anything else you'd like to mention or have an opinion then please say.
Any help please?
