If the Jetta "broke" while underway, would it be an inconvenience, or a disaster? [asked rhetorically]
The thinking here is to have an alternate TV chosen (brand, model, features) in the event that the Jetta is not what you want (after some point in time or at some point in time.)
The thinking around here is that the TT is more important than the TV. And, that the TT may itself change one or more times in the first few years. So . . the emotional relationship with the TV now becomes different than when it was just a zip-around car. Same for the TT. Stay a step removed from each. Maintain notes, keep looking at alternatives.
Towing is a strain. 67k miles is not high. But problems may start to show up sooner than later on any TV. Not to be discouraged and all. Or, really, it just isn't comfortable as imagination suggested it would (your own definition fitted here).
Bear with me here: Small is nice for either vehicle. But, it not a virtue. The experience of doing things will reveal the now shadowy corners of this venture. Building or buying, operating or owning a rig of this sort sees the biggest cost initially. After that it is incremental. Separating emotions from thinking is a matter of numbers. Now is that time for logs, appraisals, spreadsheets, etc. What we're doing is not numbers-bound . . but it keeps analyses on keel.
