Hybrid Purchase

As most of you know I am retired. Well my wife is getting ready to join me, in awhile but first we need to but a new vehicle. I thought I should at least give a hybrid a look. The upkeep on these vehicles is out of line. The trans fluid has to be changed at 30,000 miles, 15K for rough use, and it is expected to run in the 150-200 dollar range. A cover on the bottom of the engine has to be removed to change the oil and we all know how well the hold downs for these last. They also take 0-20 oil; try to find that at the local Checker. Tried to find some info on 0-20 but could not find an explanation on what 0 viscosity is.As far as repairs go I would think they are going to be a dealer only for some time, and you know my stand on dealerships, although they have improved some. I would expect this vehicle to last us about 5-7 years so it will need battery replacement at some point in time. The cost for this would be greater than I have paid for used vehicles.Also the original cost is higher, so I see no way I can come out ahead with a hybrid. Taking a long look at a Buick Rendezvous.
