I bought a set of new OEM seat covers on eBay, sold for only $500. Is it normal for them to be wrinkled like this, or should I return them?

 

I'd say that's normal. Once they are fitted the wrinkles should come out, but you may want to use a gentle heat gun or steamer to help the process. However, I've rarely seen aftermarket seat cover that are a really good fit, and they do tend to end up looking wrinkled to some extent no matter what you do to them.

 

Thanks for the reply, believe it or not these are OEM Jaguar parts. eBay is full of inexpensive parts at the moment.
