Nissan's partner installed my leather poorly

I bought an Armada w/o leather, and, at the dealer's prompting ("as good or better than factory"), used an after-market "partner" of theirs (name withheld..for now) to install the leather. I gave Nissan the extra $ at purchase time, and they took the vehicle a day or two later, kept it overnight, and then delivered it back to me (via the dealership).

The job performed is poor. I was quite upset, after finding over a dozen problems, including holes in the leather, stitching coming apart, poor/loose fit, etc. I let the dealer (manager and General Manager) know that I had no confidence in the partner, since they did such a poor job the first time around.

Not sure if anyone can give me any advise or ideas here. I went back for a meeting with the partner, GM and Service Manager, and they did what I expected - lots of talk, denial of some problems (more on that later..), and an assurence that if I give them back the SUV, the problems would be remedied. I'd rather not, but I don't think I have any choice. I gave them a few other choices, and they denied them:

• replace seats with equivalent cloth seats, and give me back my leather $
• Give me an SUV with factory leather, or put factory leather seats in my vehicle

They said they could not replace seats - against the law, saftey concerns, etc. etc.

I have also gone around to other dealers and looked at the leather in equivalent models. It is definately better, but I did find some of the same problems. Overall, though, the job is poor, and their promise that the after-market leather would be "as good or better" was false.

I was wondering, since I returned to complain about the leather less than one day after they delivered the "upgraded" vehicle, if I could be entitled to the "24 hour return" guarentee they offer. My lawyer buddy says this is possible.

Thanks for listening..
