Best new car to buy?

Am buying a new car and not to sure what to get. Reliability is the most important thing to me. My choices are Toyota Corolla, Mazda 3, Hyundai sonata, and Honda Civic. I really like the new Mazda 3 but not to sure on it's reliability.

The Honda would be the most reliable.

Stay away from Hyundai… Just returned one to Carmax because of multiple problems, a couple that Hyundai can't fix.

Sounds like good choices - except for the Hyundai - I'm not a fan of them.

Read a copy of the April 2019 issue of Consumer Reports magazine at your local library. It's their annual Auto issue in which they evaluate and rate all car makes and models.

A toyota corolla would be the most reliable. A honda civic would be my second choice. Also, Hyundai sonata is a midsize car while the other you listed are compact cars. Hyundai elantra would compete with the rest. Mazda would be my 3rd choice and the elantra my fourth choice. I guess it would depend on which vehicle i get the best deal on.

Hyundai is 4th on that list, however, since you are determined to make the mistake of buying new, it should still be considered because its warranty is better than the rest. 10 years, 100k to the original owner only.

Buy Mazda 3.
It has got a 16-valve 4-cylinder engine with variable valve timing and Cylinder Deactivation.
An 8.8-inch large center display
And 6-speed automatic transmission with sport mode.

Maruti Suzuki Swift
