No, it's not unheard of. However, most owners don't. In many cases, owners are able to afford the NSX because they spend a lot of time on their business, which means (a) they don't have the time (or, often, the inclination) to do their own maintenance, and (b) they can afford to pay someone else to do it. But to answer your question, there are some owners who do their own maintenance.Dave Hardy said:Is it unheard of for an owner to handle the maintenance?
No, none at all. Many NSX services are similar in complexity and effort to those on other cars, including brake pad changes, fluid changes, valve adjustments, etc. Some services, such as clutch replacements and timing belt replacements, are more complicated; not only do they require more time, but some involve equipment (lift, hoist, etc) that the backyard mechanic may not have.Dave Hardy said:is there any reason not to plan on maintaining an NSX myself?
If you're interested in finding out more about various NSX maintenance procedures, check out the do-it-yourself area of the NSX FAQ (which you can find on this site), the service manual (ditto), and other sites such as DanO's.
