Until how old should a car remain insured

My car is on its 6th year, previous vehicles ko would only last me 5 years then sell ko na and buy a new one. This time around, may suking mechanic na ako na pwede ko tawagan kahit nasaan ako para pick-upin ang car in case masiraan ako sa daan. So ayaw ko muna magpalit ulit ng bago, sayang kasi.

Last week, i called up my insurance to renew. Sabi nila they'll call me back, like they used to for so many years. Pero hindi nila ako binalikan.

Is it still wise to renew compre insurance or TPL na lang sa fly-by-night insurance provider sa loob ng LTO?
