I have only owned my cobalt for 1 year now and I bought it with 200000 miles on it. It currently had almost 230000 and is running strong. Right after I bought it last year I took it 10000 miles in about a month not so much as a hiccup. Last summer while I was on my trip I had all the sensors replaced on it because I had a trouble light on when i bought it but it didn't seem to effect how it drove. I got that done and light went away. I bought the car with 200000 miles and paid 2000 for it. I have already gotten my money out of it in my opinion and was happy with buying it.
