I guess it's about age and mileage. At around 125K miles I started replacing things like belts, hoses, wires, shocks, MP3 player, etc. Now at 136K I think I am through for awhile but I just added it all up and it comes to $2499.00. That's 25% of the value of my LC. Now I was wanting to get a 2000 Lexus LX470 but I kinda shot myself in the foot taking such good care of my LC over the last 10K miles. If I trade/sell and get the LX470 I am out a big portion of that $2500, man I will now feel like an idiot if I don't keep it and drive it for at least a year trying to get some of the good out of my investment. Problem is with 136K miles on the old LC something else could break and I would have to invest more. With all this talk about birfields and head gaskets going south, I don't feel safe from future expense. What would you guys do???
