The Z is a driver's car and should be driven (IMO). I would rather the car burn out then fade away...
I am fortunate to have 300+ days per year of excellent driving weather in NM so I use my 2009 370Z 7AT as a DD for work and light errands. I wash it 1-2 times per month and clay bar followed up with a wax 3-4 times per year. I still get asked if it's brand new. My 2011 Frontier Pro-4X does everything else my family needs without ever breaking a sweat.
