l am looking for a body kit for a 95 saab 900?? also would a 19'' rim fit this car??

saab sold from the factory it was called an aero kit

There was no AERO model for the SAAB 900. The AERO kit was applicable only for the 9000 range. For the 900 l think the SAAB 900 Viggen kit should fit.The 19'' rims will fit but you need to have very low profile tires, keep the same width.
Additional to the other 2 answerers
There was no AERO model for the SAAB 900. it was 900, 900S, 900SE and the Viggen. Aero was only available for 9000 on the CS platform and 9-3 AERO was introduced in 2003.

( l am not trying to be mean.) WHO PUTS A BODY KIT ON A SAAB?!?!?!??! Saab makes an Aero package which would be your best bet so the car could still keep some class.

Try saabnet.com. Great site for Saab nuts. Might be some info there. Good luck :-)
