I drive a ford focus mk1 from 1999 with almost 230k km (zetec 1.6L petrol engine)

I'm considering getting cruise control for it but I'm wondering whether it's worth it or not. Imo it drives like new but since it's an old car which wouldn't sell for too much money I'm doubting whether it's worth it. I might keep it until it rusts away, I might buy another vehicle later in life. I don't know. I do have other things that might make it worth more like a tow bar, android auto big screen radio, reverse camera and extra reverse illumination.

if I make the money back on fuel savings I think it's worth it If it makes the vehicle worth a bit more I think it's worth it.

Any suggestions? should I do it? what do yall think?
