When Is the Best Time to Buy a New Car?
Personally, I would never spend the money on a new car, regardless of any incentives offered. Nor would I ever buy a used car from an individual. You never know what is under the hood...
I would find a reputable dealership and look for a certified pre-owned vehicle that has a clear carfax report, and a make/model that is highly rated by Consumers Report or another reputable source. I'm going thru that process right now. I'm taking my time until the right vehicle comes up for sale thru a dealership I trust.
