re: Car buying preference: 3 year old luxury car or new ordinary car?

New cars are over rated
Remember they will take a huge up to 25% depreciation hit when you sign the papers

Secondly the warranty means little as most new cars rarely are repaired under warranty

It depends on the deal and the car. I would buy the Accord for the right price(below dealer invoice)

I would not buy the benz or BMW only because you are going to spend much of your money in the service bay and they are not cheap

Now the Lexus LS450 is a great vehicle and again for the right price I would drive that

It is hard to belive you are going to get a low mileage, late model Lexus in the same price range as an accord
