Buying From Thomas Acura
Thomas Acura sells new Acura vehicles and usually takes trade ins, so its used lot is a mix of brands. A certified car from the brand program comes with a factory backed warranty. A used car that is not certified is sold on the same terms as any other used car, so read the window sticker. How certified cars work.
Luxury cars cost the most to get wrong. One deferred service item can cost more than an inspection many times over.
Whatever the grade, the grade is about the dealer. The car is its own question. Ask the dealer if an independent inspection is allowed before you sign. A good lot says yes.
