Parts are a real problem, with only 115 ever made no one was keen to make spares for them. If you're looking to buy one i'd find out where some broken ones are in order to rob parts when required.
Not a bad machine but not fast at 125-130kt cruise and barely climbs OEI WITH everything done right!
Had trouble with starter buttons failing- they seemed to do this in the on position and kept the starter engaged, and with flush breakers (non-pull type) this was a major hassle.
That said, they go cheap and can be economical to fly if you can get spares.
