Cheap ebay seat covers?

[07liftback]

I found some katzkin covers on ebay for $750 + $30 S/H

For a car that I paid about $7000 for, I'd really appreciate any more constructive criticism as to why cheap ebay seat covers are bad. It might even be worth it to buy some leather seats that were meant for another car and fit it into ours. coming from the Honda world, that was always to best option because it always came with ease of install, durability, and quality.
