See if you can get a quote for the repair from the shop that made the diagnosis.

A car with high miles and a CEL on can be a major can of worms. Are you taking the word of the seller that the only thing wrong is the CAT?

he is asking $2600 for it, and he showed me diagnosis summery report so i think that is the only issue, but i want to know if i replace the cat or any other solution for it, will it make for a while.
