Sagacious Skyline

Hi All, I am very regrettably selling my beloved Skyline. 1993 GTS R33 4 Door Sedan (non turbo - Don't laugh!) Could you please help me with tips on valuation sites/methods on how to price/value it? Have tried Redbook, but can't find my exact model. Would greatly appreciate any information. TIA

Hello, Just want to introduce myself. Hi! Sadly, I have joined to try and get some info about my beautiful Skyline so that I can sell it. If anyone could give me info as to where I should be posting questions on how to decide on a value for my car that would be great.
