On 2/21 I had my car at the local dealership. After they gave me a laundry list of problems (including the $1600 “rear strut knuckle” replacement), I opted only to have new spark plugs put in and a general tune up performed.
By 2/29, my car was driving like absolute shit. Acceleration was bad and the amount of stuttering was unbelievable. The stuttering was generally occurring at shifts, so I took the car to Aamco and figured my transmission was shot (again) and that another $2000+ repair was necessary.
On 3/1 I started looking for a new ride. More on that later.
On 3/3, Aamco got back to me. They basically said that the tuning on the car was so bad that they wouldn’t be able diagnose a transmission problem if there was one.
On 3/4 I took the car to Meineke. One of the spark plug wires had become disconnected. That improved things. But things are still not right. I questioned whether the remaining problems could be due to a clogged fuel filter or possibly bad gas. They agreed it could, so I opted for the new fuel filter since I probably needed one anyway. The jury is still out on the gas. They recommended I return to a dealer to have the tuning looked into more deeply, in hopes that they would be willing to fix anything they may have screwed up. Meineke also quoted me a price on the suspension work I needed: all necessary work on both front and rear for $800. In other words, twice the work at half the price of the dealership.
So I am pleased that my car looks like it can still run for a while. That is especially important since I have zippo saved for a new car (not that I don’t have anything saved; I’ve been shoving money into retirement accounts to maximize matching and beat time deadlines, etc).
With the car still running, I can avoid having to buy anything. I was thinking about getting something used from Carmax. But it looks like the lesson there is that a newish pre-owned car from Carmax with a high used-car-loan interest rate costs just about as much as a brand new car from a dealership. And, as Rachel pointed out, the Civics on the Carmax lot cost more than her Civic cost new just a couple years ago.
I guess the lesson is that new car dealerships are OK for selling you a new car, but not at all for helping you with your used car.
