Welcome to AW. The RSX is a great car and very certinly reliable (probably wouldn't believe me that my K20A3 made it to a little over 100K race miles before it blew, stock internals). While the RSX isn't exactly the cheapest vehicle to maintain in the acura line up, it is one of the cheaper. And as far as the tranny grind issues, its usually hit or miss and its a common issues on all Honda MT's that are cable shifted instead of rod shifting. And the cure is also hit or miss. It can range anywhere from swapping fluid to some Royal Purple Syncromax to syncro replacement to a set of double carbon coated units to upgrading to some custome shift cables.
