So you said Alltracks are gone. That’s just not true. There are plenty new ones leftover on lots around America. I got a 19 SE manual (MSRP 34,500) for 25,500 before TTL with the 6 month deferment and 0% financing 6 years in April. This comes with the people’s warranty.
You already have a GTI, I feel that getting a GLI is a downgrade, or at the very least a completely lateral move that unlocks no additional value over what you currently own. The new GLIs are on the MQB platform, finally, but they’ve got longer wheelbases, and looks are subjective but I think VW could’ve done better with the MQB Jetta. It could’ve looked like a sedan Golf (like the MK5 did, the last Jetta that shared the chassis with the Golf), with good lines and consistent design language. But it doesn’t. It looks like a power ranger. And it has a trunk, not a hatch, so less utility. And it’s also FWD just like your GTI.
It’s also worth mentioning that the Jetta is VW’s bread and butter volume-over-margins vehicle. And the QC/fit and finish is likely to be a bit lower.
Anyway, having personally owned 2 Jettas and 3 GTIs, I strongly suggest considering an Alltrack. My Alltrack is by far the most unique and downright beautiful car I’ve owned, and it’s still MQB with AWD and a manual. I get compliments nearly every time I leave my house. People roll their windows down to talk to me about it at stop lights. It also gets the same gas mileage as my GTIs, on regular fuel.
It doesn’t perform as well from the factory as a GTI or GLI, I will admit. But the utility, style, and other value it provides exceeds the loss in raw performance (in my experience).
I say keep the GTI or get something that’s incrementally different.
