What to spend $250 voucher on at the dealership?
 

My 2012 Mazda 3 Skyactiv had the dash separation problem near the center gauges. I didn't know that Mazda would fix it for free until it was too late. I called and complained to Mazda that I'd had the problem for years, and why put an expiration date on a recall and so on. They apologized and gave me a $250 voucher to use towards parts or service at any certified Mazda dealership (but didn't agree to fix my dash).

So now I have a $250 voucher which isn't enough to fix my dash. What should I use it on?

I'm at 58,500 miles or so. I wondered if there was something that I should be doing around 60k that I could have the dealership do and put the $250 towards that. Other than oil changes, brakes, tires, and battery the car has had no maintenance since new. It's POSSIBLE that I replaced the engine air filter at some point.. but it's also possible that I didn't. I can't recall.

Cabin and engine air filters? Radiator flush? Spark plugs? Those things all seem too easy to be paying someone to do it, but I guess I have to spend the $250 on SOMETHING. There is no change given back, so I can't just do something cheap and get the rest in cash. If I do something cheap, the rest of the value is just wasted.

Any ideas?
