Is my Engine Healthy?
 

Now the previous owner of my car seems like he knew something about rotaries and he knew he had to go past 7k once a day but i looked at some papers and it said he only replaced coils once at 53k miles...

Right now im around 70k miles and i have a video that shows different starts:

now i haven't taken a compression test yet, but i was hoping you guys could tell me if it was even worth taking it to the dealer to get one after you watch the video

Looks like the starter cranking speed is low if I can hear it right, but it still fires very quickly.

If you want to get a compression test for peace of mind it can be quite valuable still, but I don't think you have much to worry about at the moment. Only 17k on your ignition.

And if you are at 70k then the battery is probably original and not 100%

Those starts are not bad at all. But as 9k suggested, your battery might be old too. Perhaps that could make a difference.

Not that you have to rush into buying one, but maybe a friend you lend you one for a little while that is newer, so that you can try and compare.
