For 950 you can get a decent used HV battery with 1yr / unlimited mile warranty, with free install at : http://texashybridbatteries.com/ For 995 you can get a decent used HV battery with 2yr / 50k miles warranty, with free installation at : http://hometownhybrids.com/ Both should clean the HV battery fan, and possibly the MAF sensor and throttle valve. But inquire about the MAF / throttle valve. Both can be trusted if you want to keep the vehicle on the road, but only you would know if this used vehicle will go the distance. If it can go the distance (maybe 10+ more years?), then you might want to install a new OEM for 2250+ at either of the above instead.
