shop around...
Here's what's buzzing in my mind as-of-late, YMMV...
4-yr/60k-mile service (fluids/filters/flushes/inspections/adjustments/etc): $600-800 via dealer
6-yr/90k-mile service (t-b/w-p/belts/plugs/fluids/filters/flushes/inspections/adjustments/etc): $1,200-$1,400 via dealer
'91-'96 OEM-clutch replacement: $2,200-$2,400 via dealer
'97-'05 OEM-clutch replacement: $2,600-$2,800 via dealer
4-wheel alignment: $100/dealer
Keep in mind, additional items may need to be addressed (ie. relays, gaskets, sensors, etc - due to age/wear-&-tear). It's also worthwhile to look into coolant-hose replacement, if not all of them - then the 3 large main ones for the time being.
Relative to Acura dealership service centers, independent tuner/import specialist shop will be less (25%+ less than dealer labor?), and a moonlighting/shadetree master-tech will be even less (50%+ less than dealer labor?). If going w/ the dealer, it's bests to ask for NSXCA discount and/or price-match other online dealer parts e-stores (MagAuto, Delray, Peoria, Augusta, Reno, Findlay, etc). And of-course try to workout a bundled price for services sought.
Perhaps look into...
