David,
Some purist specialists may say that the steering wheel comes from either 250 or 280 type, and that the hubcaps are not as they should be for a 230 (they should have the same color as the body), but the car looks terrific.
Before buying, take advantage of the advices on this website (there is a page with a kind of checklist for potential buyers elsewhere on this website).
Just in case, as there were changes already made to your target, it may be worth checking if other parts are original, such as the engine (sometimes they were taken from a SE). Nothing wrong for a keen buyer, but it that should somewhat affect the price...
have fun
Stan
