i sold my civic exi auto 96 model. CNG newly installed new tyres 15 incher alloy rims. now dent original paint a few small scratches only front bumper painted and all original condition for 495K with an mp3 player pioneer new. The number was special SINGLE DIGIT (XXX 1) and just replaced new shocks and all suspension.
The guy who purchased it was my mechanic who did all this work on my car.
I guess vti would be in a range of 515 with all the accessories mentioned above with original paint and good condition.
Otherwise u can deduct 50% value of the things not installed and about 30K more for a vti and a manual transmission but that covered my special registration number guess got about 10k extra for that registration number.
so the price range goes anywhere between 470 to 530 depending on condition and accessories.
good luck for the search.
