The exes, who share 16-year-old son Bentley, are joined by their current partners — Maci's husband, Taylor McKinney, and Ryan's fiancée, Amanda Conner — as they check out cars as a surprise gift for the newly licensed teen on the premiere episode of the second half of season 2 of Teen Mom: The Next Chapter.
The four carpool on the way there, during which Ryan jokes, "Maci, this is what I want to know, are you going to let him run wild like you did at 16?"
Maci considers this with a smirk, laughing as she says, "Not really."

The four agree on a blue truck for Bentley, checking it out before getting the keys to bring it home. As Ryan pokes his head into the backseat, he notes, "Oh look, it's got easy baby seat clips... just in case anything was to happen."
"Oh God," Amanda laughs.
On the ride back, Amanda and Maci talk about how much Bentley will like the car. Amanda says, "I think he will appreciate the fact that y'all came together to get it, like co-parented. I think he'll be very appreciative of it. Everything he's been through, I just think that's very meaningful to us."
"I agree. Look at us being grown-ups," Maci says.
In addition to Bentley, Maci and Taylor share daughter Jayde, 9, and son Maverick, 8. Ryan is also dad to son Jagger, 10, and daughter Stella, 5, with ex MacKenzie Standifer. He and Amanda are currently expecting their first baby together.
"Ryan and I are very excited about our pregnancy. We have overcome so much in the last year and a half, and we are in a very happy, safe place," Conner exclusively told PEOPLE in a statement.
"For me, I can enjoy this pregnancy and I have a second chance at motherhood. For Ryan, he is in a place that he hasn't been in for a long time. We are excited to move forward from our past mistakes. We have a great support system with family and friends, and they are very happy for this new chapter of our lives."
Teen Mom: The Next Chapter airs on Thursdays at 8 p.m. ET on MTV.
