I cannot comment on the actual performance of it, but from looks I can definitely say the moulded plastics look very similar to that of the losi, and if thats of any reassurance, my losi was pretty damn durable.

The only issue I ever had with it was the super thin tie rods which were made of plastic, and ended up breaking because of the constant stress of the suspension travel.

Parts support for the Losi seem to be limited to basically ebay and a couple customers on amazon (from what I've seen). Not sure who distributes Carisma, but assuming its about the same in terms of replacement part wait times.

Seems like Carisma ship with friction dampers, where as the Losi line has oil filled adjustable shocks, up to you if you want to invest in aluminum, never had an issue with mine.

For the price though, don't think you can go wrong with either one just by comparing what the Carisma looks like, maybe do a little reading on the durability of the Carisma and see what, if any, parts need stocking up on.
