RX7Club.com - Mazda RX7 Forum - ok so im a NEWB, i have a few questions about a rotaries health

ok so i would really like to get into the rotary game, but i am concerned about the rotory itself, i have heard good things and bad things, i just really wanted to get straight answers here are a few of my questions

i want a used rx7, and only one i can afford are higher mileage ones. what do i look for and with high miles whats the key to keep it alive? any major things to keep in good running shape? and if not the motor is a problem, is there anything else that is? ie: tranny, rear end, suspension issues etc.

also i live in a somewhat colder climate (erie, pa but winters get nasty) with that be an issue? (besides the RWD part)

my main thing is, i want one and am willing to put money in it, but i was just wondering if there is anything i should stay away from , or watch for? and really how to maintain it.

well i thank you all for your time, and thank you for all your input!

thanks everyone,
luke
