I’m torn on this one. I’m a firm believer of get what you love and enjoy it. You’ll always regret the things you didn’t do and it sounds like you’re doing pretty well financially. So here would be my .02:
1) why the suburban? Get the Tahoe or Yukon. Owning a house doesn’t mean that you need the extra space of the suburban. The shorter wheelbase will serve you far better for your day to day living. Aesthetically it’s identical to the suburban, just shorter.
2) What are you currently saving? I don’t need an actual answer I’m just saying it to consider everything. I completely agree with the user who talked about the Roth IRA. Start saving now and let that money grow over the years. You’ll be real happy you did in the long run.
3) Take a few minutes and write out all your monthly expenses. Netflix, insurance, food, toys, etc. it’s eye opening to see how much actual take home money you make and subtracting living expenses. If anything it just helps for a more knowledgeable decision.
At the end of the day, it’s your call and your money. If you can purchase it and it won’t adversely affect your day to day life monetarily then go for it. Get whatever you love to drive and don’t look back.
