Hoping to tap into the collective wisdom of the Mustachians- specifically the prius enthusiasts!
And that's my first piece of advice: register at PriusChat.com and ask these questions over there in the Gen II (2004-09) forum.
1) what is considered still a "newish" prius, mileage-wise? Is it the same as other cars or could we go a bit higher in mileage and expect the same performance/longevity because it's a different type of engine?
We bought our 2006 used in 2008 with 58K miles. Six years later (and after one teen driver training) it's up over 80K miles with no difference in behavior. I think you can go up over 100K miles and still expect to get another 150K miles out of the car. Worst case is an air conditioner breaking down.
2) are the maintenance costs truly lower? I've heard this about the prius, but I have no information to back it up. Is the battery truly a concern? Obviously a 2500 repair is not something we want to sign up for.
Yes, maintenance costs really are lower. No alternator or starter motor replacements. The regenerative braking greatly reduces brake wear, so you'll get 100K miles. The cooling system uses long-life coolant that lasts for 100K miles. The continuously variable transmission is ridiculously simple compared to all the moving parts in an automatic transmission.
Manhattan taxi drivers have put over 250K miles on a battery pack with no issues. There have been isolated battery failures, but very few & far between-- and mostly in the Gen I Prius.
You'll either buy a Prius that has had its 100K miles checkup, or you'll negotiate with the seller to reduce the price by the dealer's estimate of the cost of the 100K maintenance.
3) we looking for a 2004-2009 generation one, since they are the only ones I found in our price range. Any specific concerns with any particular year within this range or recalls to check on specifically?
We own a 2005 (with all the bells & whistles) and a 2006 baseline model. They're both great. My biggest snivel is that they lack an AUX jack for an iPod.
All of the Gen II Priuses have had recalls, all of which can be checked by running the VIN through a dealer or through CarFax. If the seller can produce the recall repair sheet then you're good. If they can't produce the recall repair sheet then you should reduce the price or have the mechanic check the VIN to make sure the recall was recorded as accomplished.
4) are there advantages to going through a dealer vs. a private party?
I don't think so, because you pay extra for any "advantage" of using a dealer. You'll want to have a mechanic check the car either way, and you'll probably use a Toyota dealer mechanic. But I think dealers are more of a hassle than a private-party sale.
5) Possibly the most important, because it confuses me the most- the battery. We live in Maryland. Apparently Maryland is one of the states that has the higher CA emissions standards, and therefore the battery warranty here should go to 10years/150K miles. What I CAN'T figure out is how this applies to a used prius purchase- does the car have to be newer than the implementation of this law? (Either 2008 or 2011, I can't figure out which.)? How do I figure out on a specific car if the longer 150K warranty would apply? Is it in the owners manual or something?
I think you're going to have to ask the Prius experts over at PriusChat. Someone will either know the answer or know where to find out.
Again, I think you could blow off this issue and expect the battery to perform. But I understand if it keeps people awake at night.
Final thoughts: prius is attractive because of the extreme commute, which is likely to continue for a couple or few more years. But hopefully not forever. Also we would probably dump the commuter car instead of the elantra when we eventually size up to a bigger car for me (again, a few years down the line). Normally we look at cars as very long-term purchases, so I'm not sure how to figure these issues into our decision. Resale value? Perhaps longevity is less of an issue if we're going to sell it in a few hears anyway!? I have no idea.
You might be pleasantly surprised at how "big" the interior of a Prius is. I can carry a 10'6" longboard (or a 10'6" fence rail) inside the passenger compartment. It seats five full-grown adults comfortably, with leg room & headroom. It hauls well beyond its rated weight inside the passenger compartment, and it fits a lot of stuff inside the volume. I've added an aerodynamic Thule roof rack to mine and it doesn't even noticeably affect the gas mileage.
So far so good. I'm expecting these cars to be old enough to join the military, vote, and drink alcohol.
The big issue here is that I'll need to convince my husband that it's worth going higher mileage to get a prius, which will be hard sell. And I'm not even sure it's true--- so, educate me, Mustachians! You are the best!
Well, again that requires you to be interested in selling it. And if it should come to that, I think the depreciation curve is pretty darn near flat between 100K and 200K miles.
