How else do people know when it's time for another car when their current ones currently costing them nearly all their spare money?

Hi

Wondered How else do people know when it's time for another car when their current ones currently costing them nearly all their spare money

Because sometimes because of it there isn't always much of the spare money left for some other things too

What do they do if they don't want to let their old car go or have already put so much money into them (depending on person) that's costing them a large percentage of their spare money with not a lot left,

Phones so outdated it's a iphone4 and need a new one and got to live with the old one longer

I have 2000 Camry. It cost me about $1000 per year. It's still cheaper than buying a new car that will cost about $25,000. Plus the car insurance will go up.

Because currently particular car is costing quite a bit of money at moment and is starting to need bigger items fixed and also need to update phone and can't because of that and what could you do if you don't want to change your car over
