Selling Advice

I’ve loved my 1989 Legend Coupe L with automatic since I bought it in California 23 years ago. I’d keep it for another twenty years but now I live in Brooklyn, indoor parking is $425 a month, insurance $125, and I’m only using it a few times a month. It has 123,000 miles, the gold paint job is still just about perfect (always garaged), and it’s been dealer-serviced twice a year since I bought it. Intermediate maintenance items, like timing chain, have always been done. Leather interior is great; normal wear on front seats, rear seats like new (has an aftermarket burled walnut dash, otherwise stock). Runs perfectly, including AC and audio system; the only problems are that the ABS pump is going out and the handbrake light is stuck on. I’d like to sell it to someone who would appreciate it rather than just someone looking for cheap wheels. Any advice on where to sell it and how much to ask?
Thanks!
