Most likely you will get more selling individual models vs selling the lot to a dealer,etc. But, you will work harder for it. Selling individual items will mean either taking them to shows (loading/unloading, sitting there all day) or selling on eBay (or similar) this takes a lot of time and costs money. There is no guarantee you will sell it all. If you can get a dealer to give you $10 a kit and you have 400 kits, that's 4k in your pocket and they deal with all the previously mentioned. If you go that route you will have to give up some profit on better stuff, but you will probably be sneaking in some duds too, like Nascar or C4 Corvettes.
