What are your thoughts about spending $1200 on repairs to a 1994 Jeep Cherokee with 158000 miles?

I’ve owned this Jeep since 1993 and I was hoping it would reach voting age, but it’s due for inspection and last week the muffler let go. It also has a worn right front wheel bearing, worn back U-joint, and needs some brake work. The belts are also showing their age. It’s been a great car and the engine runs good. I’ve never had a mechanical problem with it other than from normal wear and tear. I trust the garage 100 percent. They do good work although their not cheap, but you can trust their work. Any thoughts?
