I got the inline 6, 291 HP. The V8 gets shit mileage, and it's only a few HP more for a $2k upgrade, it wasn't worth it for a grocery getter/station car.
The Chevy I6 is rock solid, it's not an issue. I have a 405HP V8 in the garage surrounded by a Corvette Z06 body for when I feel the need for some ponies
I loaded it up with all of the LT options except a sunroof and nav, I RARELY open the roof on the last 4 cars that had 1, and i have a Garmin GPS/NAV 2610, so there was no reason to get that either.
Thanks for the well wishes and congrats, I already miss my X... but the TB will be fine.
