as for the oil burning, not sure, but you can take it to a smog repair station and have a computer diagnostic done on it. . . I did it and was told why my car didn't pass. . . it was $60 for the Diagnostic and $90 for them to fix it. . . Turned out to be it just needed a chemical clean and to fix a wire on my MAP sensor, but it was $150 well spent as I passed smog after that and before my car was considered a gross polluter in the state of CA. . . REALLY BAD ! ! !

As for what the car is worth, it depends on what the person is buying it for, but just being a GSR, I would think that its worth more than $1500.00, you can get that for the engine. . . www.kellybluebook.com can give you a good estimate as to what it is worth. . .
