Would you be reluctant to take a 1999 Avalon with 162,000 miles on a family trip to South Dakota? Tweleve hours one direction, and back. Concerned about the "high" miles.
The car is in good shape. Bought it from my wife's aunt at 100,000 miles. She had been takin it to the dealer religiously, and I changed the oil every three thousand. Only work it needed was the oxygen sensors and most recently I replaced the relays within the starter. So, it's been running good. But I would think that this would be the time when mechanism would start to fail.
My other option is a Buick I bought my mom recently. This one has
60,000 miles on it, a 2001. While this car has much lower milage, I don't know it very well and for some reason am actually more learty with this one.
