That's not a maintenance issue. That's "driven by assholes and serviced by cheapskates" issue.
To my great regret I once bought a ford from a dealer that I found out later to have been owned by hertz. I bought the ford extended warranty at purchase, but hertz had replaced most of the parts with shit parts, so the warranty wouldn't cover their failure. FML.
Don't buy from hertz. It's not just the drivers.
Go there, talk to a salesperson (don't, please...), and hear them out on how awesome and well maintained this car is that you're looking at.
Then you go and sign, and in the stack of papers is a form that says no warranties can be derived from what the salesperson told you.
That really means a lot to me.
For my next car I'm going to email the 3 dealerships here. I need a test-drive in a similar model, but I want a custom order (options, color combo that's never available). I'll see which ones will want to give me a CarMax experience...
Buyer in the article: It dawned on me that maintenance was too expensive.
No surprise there.
