The car doesn't look half as bad as most of the other cars I see around on forums from the same places, It definitely needs some TLC though but this is an easy car to work on and considering the market is flooded with parts for this car both factory and aftermarket, It wouldn't be too hard to find parts for this car,
Spend some time and money on the suspension, A bit on cleaning up of the body, Get the engine performing right and you'll have a fun little track car, You'll have fun beating on this car once in a while,
I don't know about the market trends or the right prices there but If the price seems right to you and you have time to work on it, this can be a fun car,
BTW! This car wouldn't be a EG-6, Since that's the code for the JDM SiR II this might be a EH-2 or something similar,
