Greetings! New Duramax girl owner in LA County California here. I bought my dream vehicle 5 months ago: a brand new black 2018 GMC Sierra Denali 2500 HD. How I got here: In 2014 I bought a brand new 2014 VW Jetta Sportwagen TDI after a year of researching it- absolutely loved my diesel wagon and put 68k mi on it before taking the amazing offer from VW due to the TDI Settlement. Had to get something that would make me feel I didn’t downgrade, and I was too in love with the diesel, so I went for what I wanted, my Duramax! Being a girl and younger than 30 and getting this all on my own was no small feat, but I’d consider myself a bit different from the average girl... 1) I’ve worked hard since I was 16 and excelled in college and reached the height of my career field more than 20 yrs younger than the average professional in my field, thus being able to purchase my truck, and 2) I restored classic cars with my parents as a hobby when I wa growing up, so I knew more about tools than my husband and am not afraid of getting my hands dirty (so little girlish cars were never of interest for me) and Love to learn as much as possible. Other than the TDI, this is my first true diesel, so I humbly admit I don’t know much about them really, so I’m really looking forward to learning and finding out all I can via this forum. I drive quite a bit for work- 15,000 mi/yr on average, and at 5 months I am at a bit over 6,000 miles (no maintenance performed yet, intending to take advantage of my 2 free maintenance services from GMC at recommended intervals per manuals). Hoping to get some insight and learn how to take care of my Denali HD (which I call Black Beauty), which I hope to drive until it dies many many years into the future. Very much into DIY or at least getting to know as much as I can about all I can- I do everything from basic house plumbing to taking down walls and reframing/putting new walls and “taping” on my own home and unafraid of a hammer and nails, which my colleagues would be shocked if they knew considering I am a top exec who works at a computer in a suit. Looking forward to learning from the brilliant and experienced minds out in the forum!
