Hi! Looking to purchase from a private seller a 2008 Lexus RX400H (hybrid) with 140k miles - timing belt, spark, radiator has been replaces within the past 2 years. The price is great ($4500). A mechanic did an inspection and said all is fine. What are your thoughts on this? I am scared this car may need expensive replacement down the road considering is a hybrid (I am fine having to spend 1-2 grand on it, but I do not want to have to spend more) and I am also worried it may already have some issue that do not come up with a regular inspection.
