Just some follow up comments with respect to your PPI list of stuff requiring repair.
- passenger wiper blade - Honda sells the rubber inserts for the blade as a replacement part. When you remove the blade be sure to retain the two steel reenforcements on the edge of the blade. You need them for the new insert. Its been a year since I did mine and can't remember the exact price; but, the cost of the insert was definitely less than $10.
- The washer nozzles are little steel balls with holes and they can be pivoted in the housing to aim them. They may be a little sticky at first; but, otherwise relatively easy to adjust. Don't use a pin to pivot the balls as the pin can go right through the nozzle and jam in the plastic in the back of the housing and break off (been there / done that). Use the blunt end of a
#67 drill bit to stick in the hole. Its a perfect fit and the blunt end resists getting jammed in the housing.
Yes, labour costs are pretty steep at dealerships and the NSX is not exactly a super easy car to do maintenance on (a cooling system flush on an NSX takes a lot longer than it does on a Honda Pilot!). I have never done a marker bulb; but, I have replaced a signal light bulb. Not difficult; but, not a 5 minute job either, especially if the retaining screw for the housing is not cooperative in going back in. Given current shop rates $37 is within the realm of possibilities. The brake disk replacement cost does seem high unless they are including the cost of new pads with all parts at dealership prices. Rear disk & pad replacement is not particularly difficult; but, if you don't have a hoist it will chew up 3 - 4 hours by the time everything is buttoned back up. Reconnecting the parking brakes can be interesting (my experience).
Some US Acura parts discounters will not ship parts into Canada. Delray Acura will ship to Canada and I have had good results from them so far for OEM parts. I have heard that Teknotic is a Canadian vendor who can provide OEM parts at matching discounts. I have no experience with them; but, might be worth a try.
As a first step, purchase or otherwise acquire a service manual for your car. I have a genuine Honda manual for my 2000 and it is invaluable. Gives you a chance to plan out the work ahead of time and make sure you have the required tools and other 'stuff'.
Its good that your ride home was uneventful. I think the view down the front hood from the driver's seat is probably the best view in the automotive world, even when the car is stopped! Modifying a car is a personal choice; but, a clean unmodified NSX will get you plenty of thumbs up from anybody who knows what it is.
Lets hope that the rest of your ownership remains uneventful.
