That depend essentially on how you drive your RC's and how many options you have when driving them; for instance if you intend to race then the marder is keeper, however, if you have areas where you can feasibly bash and want to do that kind of thing with your RC then the Baja is definately the way forward cos it will jump better, and take more of beating than the marder can without a shadow of a doubt. However, if you only have grass fields and few jumps nearby i probably wouldn't sugest getting one, as that is similar to what i did; i sold my MCD Evo 3 which had been hopped up to make it quite reliable for my use which is on the grass fields with few jumps, but then having seen all the hype on the baja, i was slightly overwhelmed and thought i was missing out a bit by having the evo 3 which usually had problems every three or foru tanks anyway, consequently i went and purchased a brand new 5t of mmr and i have had fun with it, but certainly not as much as i could've had with and evo 4, this is simply becos it doesn't handle as good as the mcd and rolls around a fair bit, and i certainly feel when driving it that i am not getting the most, and exploring fully the abilities of something i just spend in excess of a grand on. However, every time i think of selling it, i also think that i will at some point find the perfect place to take it and use it too it's maximum potential.
