Which garage is that?
The lowest cost garage I have been able to find in Manhattan (South of 96th Street, at least), is about $500/month + 18% tax ... 10 percentage points of the 18% can be exempted by applying for a certificate from NYC that proves you are a Manhattan resident - and presented to the garage.
I have calculated that it is actually cheaper than most monthly garages in Manhattan, and many in Brooklyn (especially areas of Brooklyn nearest to Manhattan), to park on the street on alternate side parking sides of the street (either Mon-Thurs or Tues-Fri), and pay the $65 ticket 2X per week: As long as you pay the ticket within 2-3 days EACH time (you do not want to risk piling up tickets and risk getting towed). Generally, if ticketed for an alternate side parking street violation you do NOT get towed ... you do risk getting towed if at a hydrant, or if on a street that has no parking 8 AM- 6 PM Mon-Fri), or 7 AM to 7 PM ... especially if you get ticketed once and do not grab the ticket (if they see a ticket already there, they will likely tow the car). Towing is a higher ticket price, PLJUS $250 to redeem the car, I think, though that could be outdated and low. Hydrants are also a higher priced ticket.
If ticketed twice a week, that is $130 per week, or $7,020 per year - but there are any holidays for which alternate side parking u=is suspended, so figure at least 10 fewer tickets, or $650 less ... which + $6370 per year.
A garage at $500/month + 8% tax is $6,480 per year - more than the tickets. But most garage slots are for more.

For me, as I am semi-retired, I sit in the car with the engine on - in which case you are not ticketed. The rule is no PARKING during the hours of alternate side parking, not no STANDING. Every neighborhood has its own alternate side parking culture ... amazing how people adapt. Thus, I only have to pay the congestion charge ($9, once per day entering the "zone") periodically, if I have to move the car to another spot for some reason, and that move forces me to go onto the highway to circle around. But that only happens about 1X per month.
