If its any help to you I just paid $16,200 for a 2004 SR5 with 28,000 miles clean car fax, one owner and 5 year or 100,000 mile bumper to bumper warranty... could have opted out of the warranty and paid $14,800 but I'm not that handy at the DIY fix'its and it gives me peace of mind!
Good luck on the purchase,
Jason
