I have a 2004 Buick LeSabre with 44,000 miles on it. I've not had any problems with the car but am not sure if I would be further ahead to trade & purchase a new car while this one has under 50,000 miles or run it until I start to have maintenance issues with it. Thank you!
Your 2004 Buick LaSabre is worth around $12K for the custom edition and $15K for the Limited Edition model, if is in excellent condition and you have performed all the manufacture suggested services. Your trade in value may be a bit less than this at a dealership. This vehicle has a high reliability rating with infrequent problems reported, all with low repair costs. I would not expect any major problems if you keep up with the regular maintenance schedule.
If you just love driving a newer car and want to drive a new car, your trade in value is pretty good right now.
