Do I have a rare car?
 

I am unsure if I really have an unusual car I can not find anything like it on line and was hoping to get some help from pontiac experts so I know what to expect when I sell this fall. It is and 89 or maybe an 88 sunbird convertible, 2.0 turbo. Any website I find says that it is rare but that is it I am debating whether this is something I should hang on to for a while longer.
Thanks for any help,
Jess
