Fixing of multiple problems

Hi there,

How to budget and stagger the fixing of multiple problems (fluid leak, broken engine mounts, and broken suspension)

I need to figure out how serious these 3 problems are and how quickly I need to get them fixed. Which ones can I wait on, which ones can I not wait on? They all see to be wear and tear problems, but they will be expensive and they all happened at once. At this point, is it better to buy a new/used certified car than to keep this car?

Problems:
(1) Fluid leak from power steering reservoir and return hose,
(2) 3 broken engine mounts -- front, right, and rear, and
(3) Broken suspension - front lower control arm bushing


A dealer quoted me the entire fix will cost about $2K.
$233 for fluid leak,
$1109 for engine mounts ($1109 = $410 for front + $262 for right + $437 for rear mount)
$555 for suspension

The driver (my mom) is very bad with cars. So I was thinking of fixing this car and having her drive it to death. However, I care first and foremost about her safety. So I want to do what's right within my budget (hence the need to stagger some of the fixes).

Thank you so much for all your help!
