Would love to partner with Hemmings. If you'd like to see their listings on AutoTempest, please reach out to them and let them know!
No idea when we'll get to this, but we're still planning to do it eventually.
Adding more filters is one of our top priorities. We have a number of new filters planned. Not all the ones in this list will be possible, mostly due to the data we have available, but we will be adding what we can.
Planned for a long time, I know, but we've wrapped up some other projects and will be getting to this soon.
Absolutely agree that we should have email alerts. We are working on some other priorities at the moment, but it is planned. Price change alerts are an interesting idea too, and one that we hadn’t considered before. I will add that to our list!
In the past it was different because our results were sourced from multiple sources, some of which did not support this sort of automated updating. That has changed recently though, so this is something we are planning to add in the not too distant future. Our small team just has a couple of priorities to get through first. (The biggest one being improving how makes and models are selected, so you can enter your own choice and optionally choose from an autocomplete list, rather than only choosing from our lists.) We are definitely planning to add alerts when we can though!
