I've done maintenance on my vehicles sense I was 16 years old(I'll be 50yo next month). There certainly has been jobs that I simply didn't want to tackle on some other vehicles. But I enjoy doing things myself and learning about the vehicles that I own. We purchased our 2011 Grand Sport 7 months ago and so far I have changed the oil, replaced the brake fluid, flushed/replaced coolant, replaced clutch master cylinder(TSB), swapped to Ceramic brake pads, installed a MGW shifter and swapped over to full Z06 exhaust. I'll be changing the diff and trans fluid in the near future sense I have no record of it being done.
