I've been contemplating purchasing a RX 400h with 86,000 miles. I want to know what you all think of buying this high mileage vehicle. It appears to be in immaculate condition; interior, exterior and under the hood. Part of my concern is this: is there going to be things I immediately need to replace or fix? Timing belt, CVT maintenance, brake maintenance? I know I could probably pay a tech to do a once over on the vehicle before I buy it, but I thought I would ask in this forum first. Is there any telltale things I should watch for when I test drive it? Things I should ask the dealer about? I'm new to hybrids and to CVT's.
