Buying a Car again?

So I enjoy putting food out for the TROLLS while getting some pretty good advice from a few wise members about finance.

This time I want to make sort of a game of scenarios where you give your (good or bad) advice about the financial situation in each scenario.

So here we go:
Assumption: These people need a car.
What car should the person in each scenario drive?

Assumption: These people have no investments and just cash savings
What should this person do with their savings?

Assumption: Retirements is being maxed at 5k per year.
What should this person save per paycheck?

Others?

1. Scenario 1
   Age: 26
   Income: $80,000 yearly, monthly = $5050 after tax
   Savings: $15,000 , Retirement: $10,000
   Monthly Bills: $1600
   (Bills include: Apartment, Married income 120k yearly, Student Loans 30k)
   
   
2. Scenario 2
   Age: 32
   Income: $73,000 yearly, monthly = $4240 after tax
   Savings: $25,000 , Retirement: $25,000
   Monthly Bills: $1900
   (House, Single, Student Loans 15k)
   
   
3. Scenario 3
   Age: 50
   Income: $115,000 yearly, monthly = $7260 after tax
   Savings: $5000 , Retirement: $10000
   Monthly Bills: $2400
   (House, Married income: 170k, (1) Car payment for wife $450 monthly on a 42k car)

Have fun with this one. Interesting to see what you would do in these situations.

I will evolve this thread as I see responses and what the conversation will look like.
