should I????

k, first off im 19 and i've been in love with the 510 for like 5 years and finally i found one but it's needs some work, ( decent rust on the rocker and rear quarter panel) the engine is alright but i will be putting a good 8 G's into the car if it's worth it the interior is shot.....the car cost 2500$ canadian good deal? and if u have any tips for plz help, thx

btw way I'm also looking at other cars ei. WRX sti, evo 8, 350z and '96 m3. just want some thoughts on what to do

Make sure that the tops of the strut towers are not rusty, and if they are, have someone take care of that properly before it gets out of hasnd because I have heard to many stories of people losing 510 when their struts punch through the tops of the strut braces and the car either drags on the ground or crashes into something and ends up beyond repair.
Other than that, just find someone that knows the cars real well and extract everything you can out of them.
