Benzfan thanks for your reply....nice to know yourre from Toronto!
Me and my father were discussing all of this and yeah we couldnt figure out why a aftermarket cat converter wouldnt work!? It did on my dads Grand Cherokee and my old SEL. He did aswell go to Noizeboys
Another thing I forgot to mention is the trunk lock tumbler is either seized or something....doesnt turn with the key. He said its $900....I said WHAT!? Prob another load of crap at this point.
We've come down to the conclusion (and hope its the right one) the car is obviously not new anymore and just needs some basic TLC and its own maintenance but will try and get the used car dealer to do as much as they are willing to.
As far as warranty it comes with a 2yr powertrain type warranty (engine-tranny) but for $400 extra u get one which covers the AC and some other stuff with unlimited mileage. Probabaly should get that!
The engine and transmission on the car checked out perfect and no leaks anywhere. Car has minimal or none rust. MTO papers showed no accidents or salvage.
If anyone else has extra info please chime in.
