I would steer away (so to speak) from wheel adapters. They are a kluge
at best and dangerous at worst.
4x100mm is a _very_ common size. Supposedly, there are 850 different car
models with 4x100mm wheels:

and about half of those have a 38mm offset (ET):

The diameter of the center hole (DIA) is the next selection, but
this is generally not an issue, _if_ you measure your car hubs and get
one that size or larger. Looking briefly, it seems most VW's are 57.1mm,
and there are a lot of models to choose from. Again, you should check
your vehicle and see what the actual hubs, both front and rear, measure.
The Scirocco, for example, had 14, 15, 1nd 16 inch rims in a
4X100mm bolt pattern, 38mm offset, and a 57.1mm hub diameter. The 14 and
15 inch rims were, however, "replacement" wheels, likely supplied as a
"deal option".
BTW, I have bought aftermarket rims for my cars for perhaps 20
years to mount my snow tires on. For quick change in the driveway when
the snow hit. No issues ever.
If you need help with wheels, there is no one better in the world
than Woody's Wheel Works in Denver. (Notice that I am wearing a Woody's
hat in my profile.) They don't really sell rims, but they are the
world's experts on repairing damaged rims, and building custom wire rims
for cars and motorcycles.

David, thanks, I'll look into the Nokian's. 185-65/14 will work
although I'd prefer them in 60-series tires.
This ~would~ be a whole lot easier if I was willing to bump up a wheel
size, but there are multiple issues to deal with, clearance issues,
style issues and worst of all, wheel issues.
VW does not make an OEM 15" wheel with the required 4x100mm bolt
pattern. Aftermarket wheels seldom run true enough for my taste
because they are universally lug-centric instead of hub-centric. The
other problem is that it's kind of a crap shoot as to what the offset
of aftermarket wheels is going to be. Factory offset for this car is
38mm. The wheels I put on this week are VW OEM 14" 45mm offset, and
195-60/14 tires are within 2mm of rubbing on the rear springs, and are
interfering with the body in the front on locked-steering wheel
movement. I avoid after market like the plague (oh yeah, that's a
totally relevant excuse these days!)
I *could* buy aftermarket wheels (assuming I could work out the offset
problems) and then have hub adapters machined for them. Oh boy,
another project.... If I actually needed another project, I'd have
replacement front wheel hubs machined to accept VW's range of 5-lug
wheels. The rears would be a bolt-on disc brake rotor swap. I have a
recycle yard stocked with those type of parts at my disposal.
Yes the Invicta's were noisy. Especially for me because my car has
autocrross-prep suspension, urethane pivot bushings throughout. They
were also uncomfortably like driving on ice all year 'round as well.
May well be that a small tradeoff in energy efficiency will be worth
the added ride comfort and traction.
