Rust Issue

Perhaps this might help…….
I had 2002 H2 with 11,000 miles on it.
When I got “tired” of issues I tried trading it for new H2.
Dealer offered $32,500 for mine, we settled at 34k.
And one of the arguments dealer used was …. Take a deep breath…. Unpopular vehicle with issues.
Next to rather long list of repairs and few beyond repair things, with that altitude I just went to MB.
Got myself G500 and got 37k for my H2.
I still love H2, don’t understand me wrong way, it’s just that I don’t like being showed around.
I had rust spread all over the undercarriage and I took care of it. Removed it, primer+paint+marine type inhibitor.
Did good. Than I found rust under the carpet behind rear seats, cargo space. Huge rust spots!?!?!?
Tried cleaning it just to discover that one, next to the RR wheel well was “see-through” spot.
Similar on driver door. Bottom inside with heavy rust.
I agree, it’s the first run and small glitches are to be expected.
I just didn’t want to end up with rusted H2 even before warranty expires. Yes, this is Chicago, land of road salt, but still....
