Should I keep my 2003 with 140,345 miles Chevy Tahoe?

Edit to above...I just found out the clicking upon start up in cold is affectionately NOT know as piston slapping...common in GMs. Embarrassing though.

I still have my 2003 Tahoe and it has over 290,000 miles. I have taken care of it. The transmission does slip a little when shifting and my windshield wipers don't work. These are repairs that can be made easily. I love my Tahoe and haven't found a single vehicle that compares to this year model and make.

Thanks. Relieved to know. Keep my great car and more $ in the bank! We took care of the piston slapping and bearings and heat a few days ago...sounds great. Continued enjoyment with yours!

I have a 1997 Tahoe - am going into Buffalo today to pick it up at the shop. Had several necessary repairs made, aging of the vehicle and rust were causes. Transmission lines replaced, gas leak fixed, power steering and brake lines checked, all adjustments needed to pass inspection made. It has between 250,000-300,000 miles on it, bought it lightly used in 2003, under 47,000 miles on it then. I love this car - getting a newer Tahoe would almost be equal to a mortgage! I won't say how much these repairs are costing, but it is still less overall that a monthly payment for 5-6 years, probably on a much smaller car with more computerized aspects to go bad. Hang onto your Tahoe and baby it.

Update to my question. Well its now 2016 and my 2003 Tahoe now has 150,000 miles on it. Now ball bearings need to be replaced. It started to feel really mushy. Quoted $1300. Thats ok, its still my baby and I love it, however dont trust to go on long trips say visiting out of state colleges etc. Bought a 2016 Tahoe, sight unseen. From an internet dealer for $43,000 before tax n tags. I was looking for used and only wanted to spend in the 20s. They happened to be all govt cars with lots of cosmetic problems, high miles. Even newer used cars like 2010s all had @ 97,000 mis on them and were selling for $30s and with that mileage Id b in the same boat im in now in a few yrs. So got brand new. They even delivered. Had to act by Feb for all the discounts. Buyer beware from local dealers who do not always disclose all the discounts you can get. Research online. There is a GM loyalty discount. Anyway, new car feels huge, the hood goes straight out, no slope so need to get used to parking. Windows are smaller, thats what I didnt like on all the new suvs like buick enclave and ford explorer. Plus i always banged my knees in my parents enclave. Im 5'7" thin woman. Need a PhD to figure out fancy electronics. Wish I could have forgone all the fancy stuff. Including back up camera. I like the old fashioned turn head around when backing up. I dont know how I feel about 1 less seat b/c of the 2nd row captains seats. Also the cargo floor in back is the back of the bench seat when folded down which eliminates headroom Id say by 6". Also drivers side seat a lot higher so I set it on easy out. Lets see when the seat electronics break with use. Fyi the 2017 i believe will have a V6 and many changes like no am/fm radio or cd i think. Not all of us want to spend $ on sirus. I will let my free trial expire. Onstar too, but free for 5 yrs. Im glad I will have another reliable engine for another 20 years. At 70 yo by then I hope I will still be able to get in and out. I still love my 2003, its like an old comfortable shoe.

@luvmytahoe do you still have your truck?
