Tips on Buying Cars: New car buy, lexus models, misko

Question
Ray,

Thanks for taking my question.  I recently wrecked my car of 7 years and I suspect the insurance company will rule the car "totalled."  If not I may rule it that way myself.  Although the wreck was minor in terms of impact the damage was pretty severe.. front passenger side wheel snapped at axel, both air bags deployed and broken front windshield and dash severely damaged on passenger side.  All that side my question is pretty subjective.. do you have any recommendations on a nice 4 door sedan?  I'm looking for something under $40k and while I've never bought used before would consider buying used from somehwere like Carmax etc..  Have looked briefly at the Mercedes and Lexus models.  Also, any thoughts on leasing vs buying... I've heard that leasing can be great but only if you own a business?

Tks much

Hi Harrison
Having just returned from a weekend away I noted expert Ron Misko has answered this same question, I read Ron's answer and found it excellent in detail and there is really nothing I could add.
