Why would you take the time to search different places for such a cheap part? You can get it for $18.50 at PJ Grady, and you know it's the right part. You know you're not going to overheat your engine with the part being correct. Is it worth taking tons of time out of your schedule to "possibly" save a few dollars? I understand looking for items that are a lot more costly at your local store, but really... Remember, if you don't buy your parts from a DeLorean vendor, they may not be around when you need a DeLorean specific part.
The part number is 102709G and they'll ship it right to your door. You may not know this but, not all thermostats are created equal. There are cheaper, less reliable thermostats out there. Saving a few dollars could cost you thousands in this case if your engine overheats. The thermostat from PJ Grady is the best I've ever used. It's been working flawlessly for me for years.
