Mazda Miata or rx7 or nissan 240sx or other

hellooo I am a new member to the forum, just signed up but not the first time here. I am 17 years old and from Canada. I'm looking for a good first car to own. My budget is $5000. On the top of my mind three cars pop into my head. Miata, rx7(na), 240sx. This car is going to be a daily driven. Fuel economy is not a problem. Suggestions..............

240's are everywhere so parts are cheaper.
Miatas in the higher end price range and well, its a miata
RX can be costly and whatnot, but if you find a good one then it can be a great car.

i own both a n/a rx7 and a 240sx.

rx7 can get expensive when you go crazy, but the 240sx can be even more so (with the popularity of sr20det, jdm parts etc, if thats your style).

if its going to be your first car i recommend the 240, unless you want to deal with a medium high maintenance car like the FC.

also (i cant speak for canadian insurance companies) but when i switched from my rx7 to my 240sx i saved $60 (usd) monthly for insurance
