1999 Civic EX Coupe 5spd Manual (on original clutch with no evidence it'll need replacing soon) 165k miles Dark Green Color, with aftermarket rims and new CD/MP3/USB Player No engine or performance mods. Most maintenance done at the dealerships. Replaced timing belt at 90k, Cat at 140k, A/C compressor and accessories at 140k (though it only seems to blow 25 degrees below outside temp now, man I sweat). Edmunds says trade in at 40, Private sale at 95, and dealer retail at 49. Yet, the NADA site says low retail at 75, clean retail at 00, and High Retail at ,400. That's a big discrep. It's a clean car, but by no mean immaculate... it's very used. But if I trade it in, I have no idea what to expect. Any thoughts?
