Are you serious?
My guess: too many miles on the WRX, harder to insure, almost 10 years old, and general wear and tear forcing him to downgrade in size.

Coolant Temp Sensor
Thermostat
Oxygen Sensor
(those three are probably the reason's why the thing gets Excursion like gas mileage, I got gas on Monday morning and I'm already half empty...what the fuck?!)
Spark Plugs + Wires
I've had the car for 4.5 years. And I'm sure I've traveled more than 30k miles. Whoops...
The coolant temp sensor and thermostat would only need changing if the car is overheating.
Many new cars use the coolant temperature sensor as a reference to know which fuel map needs to be selected for a given timing curve. So there is some validity to his statement.
Saturn Forum said:This is one of several ?hearts? of the system, which helps maintain fuel economy. The original ones from 1991-mid 2001 (it?s virtually impossible to tell when the changeover happened) were made of resin/plastic, which liked to crack, causing incorrect readings to the PCM.
Saturn Forum said:Whilst not a common issue, it?s worth mentioning, as it?s the third ?heart? to maintaining good fuel economy and emissions, as this also controls the open/closed loop operation. It is the last to warm up as part of the car?s normal operation. If it goes into open loop when it should be closed, you can experience rich running; if it goes closed loop when it should be open, it will run lean.
Saturn Forum said:This is another ?heart? to maintaining good fuel economy. It can also help with having good, toasty heat in the winter. Old thermostats like to fail in one of two positions: Open, which doesn?t allow the engine to reach normal operating temperature (at best the gauge will peg at ? line or ~160 degrees F or LOWER ? BAD NEWS for your engine and heat!), or closed, which will allow for the kick-butt fuel economy AND heating, but has one downside: it can cause your engine to overheat. More often than not it will fail open though.
Pft, my car is 10 years old and has never had a sparkplug change.
Let me enlighten you a little bit. Only the oxygen sensor is causing your poor gas mileage. The coolant temp sensor and thermostat would only need changing if the car is overheating.
About the spark plugs - I call bullshit, but that's my personal opinion. Many people say that you should change them every 30k, and that's probably a good idea on an enthusiast's car. On a daily driver - hell no! You change plugs and wires when it starts misfiring. Contrary to popular belief old (but still working) spark plugs do not affect gas mileage.
If I had these same problems on the Volvo I would just fix them (they don't cost that much), but in your case I understand your desire for a new car
6 weeks and I'll have enough for a new used car. Believe it.

This. It's not newer cars, and it's not just selecting between maps. Anything that's fuel injected with a coolant or cylinder head temperature sensor uses that sensor to determine fuelling - whether it needs to run full rich because the engine is cold and just being started, or lean it out because the engine is up to temp. More importantly, it's used to constantly adjust anywhere between those two points. The CTS/CHTS is your primary sensor for determining the base fuelling mixture in EFI systems.
Was it a dealer plate? The Tacoma could've been bought at a Mazda dealer that have "Zoom-Zoom" on their license plate frames.
