Question about reliability of other Chevys



Hey guys,

My girlfriend is looking for a 4 door car that is reliable. She isn't like me in the sense that she wants a fast sporty car, she mostly wants something that is good value for her money, and reliable.

She is looking at:

1. 2017 Acura TLX
2. 2017 Chevy Impala Premier V6
3. 2017 Lexus IS-250

Also, I tried to talk her into the Cadillac ATS, but she says it's too square...

So basically, my question:

I know that the Camaro is a reliable car, but how does Chevy make their other cars? Is the impala a good car? Is that v6 engine good? Any known issues? I think obviously the Acura is probably the most reliable, but are present day GM cars behind at all? Or on par with Japanese cars

Please let me know

Thank you
