Buying a new (used) car though a service

I have seen several ads for services for buying a car. USAA has one as do several others. Has anyone used Any of these services? I know I may have to man up, do the research and go lot to lot But… I wanted to know if anyone has used Any of these services… Thank you.

I have not used one, but you can’t get much moe reputable than USAA. Read the ads closely. Is it really UUSAA or is it someone that advertises in a USAA publication? If it is an advertiser, contact USAA and see if they have vetted the advertiser. Publishers often (almost always) accept ads without checking for truth in advertising.

good point. I will do that. I also see Costco has a service as well…
