2004 Toyota Sequoia Leather Description

This vehicle is being sold as-is, where is. I drove this vehicle for several years and had regular maintenance such as oil changes and tire rotations. We used it as a family vehicle. As you can see in the photos it has exterior and interior cosmetic conditions including torn and ripped seats, body work, small dents, and basic to heavy wear that you would expect to see on a vehicle of this age and mileage. In January I put a brand new set of 65,000 Good Year tires on it; In May it had new brakes, rotors, and calipers installed including having the breaking system flushed. At 100,000 miles it had a full tune up done at Toyota which cost around $3,500. I still have the paper work to show for it as well.
I recently was driving it when the engine starting knocking heavily and making noises and losing momentum. I took it directly to my local mechanic shop who is reputable and has been in business for 20+ years. He stated that he found 2 broken spark plugs and that the valve gasket needed to be replaced as well as other "top end" engine work that needed to be done. He also stated that he could not identify exactly what was wrong with the car but that it would be at least $750 worth of work that needed to be done and that he may find more things wrong with the engine once he started to take it apart and look at it. In addition the car power door locks stick sometimes, all of the windows work with the exception of the rear window. Although only one of the 3rd row seats is shown I do have the other one and it will be included with the vehicle.
I must say that I know absolutely nothing about car mechanics and that I am taking his word for it. I truly do not know the extent of work that needs to be done. Although the car starts and runs the mechanic stated that the car would probably not run for long before breaking down so I would think that the car will have to be towed. I paid for a diagnosis and in the photos you will see a list of items that the mechanic found wrong with the vehicle. I will try to answer your questions to the best of my ability with the information I have.
It was a great, reliable family car for us, a true work horse. This vehicle is being sold as-is, where is for parts or repair.
