Brought my car in yesterday and they replaced my timing belt and water pump. I also brought in a 10% coupon which they reluctantly accepted. Couple hours later, they call me and tell me that I need to get the cam seals replaced, which would cost me 224 dollars. If I hold off, it would cost me an additional 200 bucks. Is it common to get cam seals replaced on an NSX? I might just be getting paranoid about all this but at any rate, the 10% coupon was negated and I ended up paying more than I anticipated.
