Fully understand, my work commute is like 8 miles, as I recall yours is much more than that. I do drive a lot, might not mind it back there if it is real clean and make a box for it. I am going to New Jersey this summer and a spare would be very nice, had one flat in my ECO and by the time you get towed and repaired it isn't much fun and that was during the week and at the end of business hours. On a weekend or at night would be very disruptive.
Is the Verano spare a 16 inch doughnut? How would that work if especially on the front? Just curious.
If it works one can be picked up at a salvage yard for $50-75 which would be fine, plus I have the kit that could work as well if needed. If purchased at salvage yard need the little handle thing to remove the nuts that hold on the wheel as well and a little jack of some sorts. Would have been easier to included in the car from factory, hope the 17s have a spare.
