I had an 03 cts but traded it in for a Tahoe as i now have a family of 4 but the V8 is burning WAY more then the Est city MPG. So I'm considering either a MB E350 Or a 08 cts but I was reading about the timing chain issue witch is my main concern, has anybody had any major problems/ COSTLY repair and would any one recommend this vehicle I loved my old cts but it was just a little to small in back. I know these are suppose to be more little more roomy so could it fit two car seats comfortably? Any insight on the car would be greatly appreciated ! Oh yeah I'm looking for a higher miles car maybe 75 plus so keep miles in mind or if its a bad idea please just let me know!
