Would a 2017 Mustang EcoBoost Premium be worth buying for around $19,800 in 2026?

I’m currently 22 and would be 22–23 when buying my first Mustang. I live in Mexico City and want something that feels sporty and special but is still comfortable enough for city traffic and longer highway trips.
I found a 2017 Ford Mustang EcoBoost Premium automatic for approximately $19,800 USD. It has around 22,400 miles (36,000 km), four driving modes, two-tone leather, 20-inch wheels with new Michelin Pilot Sport tires, the original Shaker audio system, heated and ventilated seats, navigation, a backup camera and rear parking sensors.
The car was recently imported from California into Mexico.
I don’t really mind that it will be almost ten years old. I actually like the S550 design, and my plan would be to keep it mostly stock and only replace or upgrade the infotainment system with a modern wireless Apple CarPlay unit.
Would you consider this a fair price in 2026, assuming the mileage, clean title and import documents are legitimate? How reliable is the 2.3 EcoBoost with the six-speed automatic at this age, and how difficult or expensive should maintenance and replacement parts be over the next five years?
For comparison, I could sell my current car for approximately $11,150 USD, so I would need to add around $8,650 USD before inspection, registration, insurance and initial maintenance. Would this be a sensible first Mustang, or would you wait and spend more on a newer model?

Can I driver daily on the sport or track modes

So I got my car about 4 months ago and decided to finally try to look at the features on the touch screen. I’ve been able to update the colors and stuff but haven’t played around with the custom driving modes.

Can I use the sport and track custom modes to drive in each day? I live in the city so don’t drive far or do anything wild. I tried the track one yesterday and I feel like the car sounds louder which was fun. It did also feel like the car has less traction/control/stiff. The sport idk if it feels or does much different than normal?

I couldn’t resist but taking a picture

I wish my car was cleaner with fewer bugs, but the lighting was too good not to take advantage of.
This is my 2019 Velocity Blue Mustang!

Mustang Stalled, what should i do?

2021 Mustang EcoBoost randomly stalled while stopped in Drive

I have a 2021 Mustang EcoBoost with around 80k miles. Today while I was stopped in Drive, the car randomly shut off. The dash then told me to shift to Park to restart. I shifted into Park and it started right back up.
The battery was replaced about a week ago after it tested bad, so this wasn’t immediately after a battery change.
I’ve also been dealing with an intermittent vibration/rough idle for a while. It mainly happens when I’m stopped in Drive with my foot on the brake. RPM will sometimes drop to around 600, the car shakes/vibrates, then it goes back up around 800 and smooths out. It seems to happen more often with the AC on. It doesn’t really happen while I’m actually moving.
No check engine light and scans haven’t shown any active engine codes.
Has anyone had this happen with an EcoBoost? Could the rough idle/RPM drop and the stall be related? What would you check first?

update- this happened again the next day, after my engine had been warmed up. I have also had the purge valve replaced about six weeks ago, not sure if there’s anything to do with this.

2024 EB muffler sound

I recently bought a used 2024 Mustang EB convertible premium. I do have the 200A package.
I have 2 questions.

  1. how do I know if I have the S550 or S650?
  2. how do I change the sound of the muffler? There is an icon “Sound” but it is grayed out. Am I looking in the wrong place?
    Thanks

Back in the saddle!

This is my fifth Mustang and the first I’ve had in 14 years. My love affair with Mustangs began in 1995 when my big brother got a brand new 5.0 GT. I was in love with that car. He later bought a 2002 GT and he let me drive it, now I was hooked! Eventually I saved enough to get a 1993 LX 2.3. A whole 105 HP! 0-60 eventually. Soon upgraded to a new 2004 V6 Pony Package. Then a 2006 Pony Package. Later on got a 1998 GT, I finally had a V8! Had so much fun in that car until a rainy day and slick tires (my bad) made me hydroplane into a wall. No more stangs until now. This Ecoboost puts all the old V8s to shame! I’m so happy!

Help Me Pick The Ecoboost

I decided to buy a mustang ecoboost. I have a trade in that carmax offered to buy for 8000. I have about $26,500 saved up for the car.

I narrowed it down to 2 options

New Ecoboost 101A Base with Active Exhaust Valve for $22,500 + My Trade in

16,000 miles 2024 Ecoboost Premium with HPP + Active Exhaust Valve and B&O speakers for $25,500 + My Trade in

I can’t decide because the new one has 3 year warranty and the used one has so many options on it.

Which one do you guys think I should pick?

Is this too many miles or a car worth buying

It’s a 2022 eco with 10spd with the stealth package which I really like. Car is a two owner and has roughly 56k miles on it. It’s currently listed for about 23k but I believe I can get it down a little because my brother has buying history with the dealership. Is that too many miles or would you consider buying?

Yes 5.0’s are cool but I feel they’re more common than ecoboost

Don’t get me wrong the V8’s are awesome but I’ve really fallen in love with the ecoboosts because they’re cool for what they are and they’re like a JDM mustang and with the the right exhaust (takes some work) they can sound really cool

Catch can recommendations

I’ve been running the driver’s side ford performance oil-air separator. It’s been working just fine up until recently, and it still works, but I’m certain the heat from the engine bay warps the plastic. There are gaps where it should be sealed. I can see the gasket at various spots and oil sprays onto the driver’s side strut tower.

I’m now in search of a catch can that won’t cause this issue. Preferably one that isn’t plastic. Any recommendations?

Dealer quoted me 6k for a cracked flex pipe and timing cover gasket.

Hey all, I own a 2019 mustang ecoboost and took my car in this weekend for routine maintenance. During their inspection they found a cracked flex pipe and theyre wanting to replace the whole catalytic converter. I was quoted 3k for that. They also found an issue with the timing cover gasket thats causing a small oil leak. 2.5k for that. I am not looking to get this done at a dealer as I know they upcharge like crazy.

Looking for advice as Kelly bluebook has the car priced at 12-15k at my mileage (70k). Wondering if I can get the cat for free by bringing up federal emissions warranty. Emissions test is due in 2 months. What kind of savings would I be expecting if I took it to a local shop, for those that have had to deal with this? This was at a ted britt Ford in VA.

Thank you in advance!
