My Mechanic did some checking for me. Type SH preludes parts are across the line 20% more expensive. Even if the part is the same, Honda will have a different part # for the SH and ding you 20% more. How are you supposed to know if the part is the same as the base or different?
If you buy one with high milage out of warranty you will have more expensive repair bills with the SH. The SH is a fun car, but so is the base. Try both and see which one you and your pocket book like.
