Hey Sir

If you need the "Z" as a daily driver,
remember that always something can happen to the engine (Cross Fingers)

I myself have every year, spent 3k extra for additional.

- New ECU setting
- All 3 - 5k Miles an oil change and full inspection
- New catalysts (are burned after every 10k miles)
- Higher tire wear
and so on......with a boosted Car

As written above,
a budget of 20-25k is absolutely realistic
