You guys are looking at this from one angle, finding the cheapest way to get these parts. If you want these parts and you want them as cheaply as possible, then this is not worth it. But put bigger wheels on the car and if a wheel bearing blows, a dealer MIGHT try to tell you that you changed the wheel to a different diameter which caused excessive spin/wear on the bearing so its your problem.
This is a good car, modified by a reputable shop, for a dealer that is willing to cover the risk of parts installed. Remember, when you bring a car for warranty work, coverage under warranty is first evaluated by the dealer, then when they go to the manufacturer for reimbursement, it is evaluated by the manufacturer. The dealer must have some monetary safety net for them to accept the risk of modifying a car in the event that a problem does arrise, it is found to be covered under warranty by the dealer, but is not covered by the manufacturer. Plus they probably add a few $ to give them some breathing room for negotiation in the sale. If you know nothing about modifying cars, this would be a good option. If you know something about modifying cars then it's probably better for you to buy these parts separate.
When the car was first released, dealers tried adding cheap leatherette seat covers, tinted windows, chrome wheels, all kinds of nasty half assed over priced mods. I applaud Longo for not only attempting to have some connection to the car community but also employing a reputable shop within the community to make sure the modifications are quality and are done right.
