I need to repair the front seats on my '02 Cougar. I've bought the replacement foam, and I now need to make a decision about repairing a couple of leather panels on the two seats that are wron. I've found a shop that will install the foam and replace the leather with new pieces for $450. The same job with synthetic leather would be $300 at this shop and another I found. The second shop argues strongly for the synthetic, since it's cheaper and needs less maintenance. I'm inclined to put the leather back in, but if the synthetic is better in some respects, and cheaper, I'm open to the synthetic. Any opinions?
