Well if its a twin, it will be reliable like the triples except with a bit. Well, A lot, more gas, so more trips to the gas station and more money, but as for reliability the have no problems, im just goin' by what other people around this and other forums say about it, but if you know for one sale, how much is the seller asking??? How many km's (miles if your in the US) and if its in good overall condition will determine what its worth.
