We might be on different pages when shopping for vehicles but it wouldn’t be a good deal to me. Good deal to me would be: I would try to find something in the 12-15k miles/yr category, Lexus maintenance records help the cause if they are consistent, include Lexus recommended services and bigger ticket items have been done recently. Side note - are the wheels mismatched finishes? I would also want more details from the Carfax on where it has been and how many lovers it has had.
Good deal based on price alone? If that is what your budget allows, it checks the first box. Unless your budget gets destroyed because it has lots to bring it back to Lexus standards.
PPI would help build confidence along with a traceable road map of its’ maintenance. At a high level, It’s a good deal if $12,800 doesn’t put you in debt and you have to have a V8 Lexus. Many more layers to an onion than just the outside. IMHO.
