and I have no good idea what to get the happy couple. Background: Nick is 23, an auto mechanic at a GM dealer. Christina is 22, graduating college with a degree in accounting. I am going to talk to both mom’s and nick’s oldest brother. Any and all ideas from the TM’s would be greatly apprecated. MTS
You could see if they need any help financially in planning the wedding and help out as your gift.
Depending on how much you want to spend, you could send them somewhere really nice for their honeymoon.
I could probably come up with more ideas, but it’s late and I’m tired. 
Congratulations on your son’s engagement!
