hi, im new to the rx 7 world of rotarys

i just purchaced a old rx 7 90',has 253,000 on it.. and im not sure what model is it if its gxl or..
1. how could i tell *doesnt say one the body*
2. what should i do immediately in order to make the car last... since it has loads of km on it
3. the sun roof is broken.. (last owner says i need to replace the roof motor), can i buy one and fix it or do i have to bring it in a shop?

 

you should definitely get that engine checked up on. I don't think it will last past 300,000. You're definitely going to have to do a engine swap in the next couple of years.
