I've bought 3 new GM vehicles this quarter (2015 Silverado LTZ, 2015 1/2 Escalade Premium ESV, 2015 Corvette Z06 A8 Roadster), so am suddenly familiar with GM's offerings and how they differ line to line.

I'd like to suggest a 4LT/4LZ package that includes the equipment my wife's truck has that my car does not, such as:

- Blind spot warning mirrors
- Cross traffic alert
- Ultrasonic park sensors (in 2015?)
- Driver alert package (and I think the Escalade adds automatic braking)
- Etc.
- Distronic cruise

Basically, all of the equipment you can get in a Cadillac truck and a Chevrolet Highlander but not Corvettes's highest offering.

I appreciate the boy-racer crowd could care less, but if you look at a Mercedes CL65 as an example, there's a place for GT cars as well. Particularly in convertibles where track use is moot anyway.

Suffice to say, I would have purchased this package had it been available. Of course if there's a reason never to exceed 3 in the option code, put this stuff in the 3LZ and keep 1LZ and 2LZ light.

Thanks for listening, whoever's here. And to summarize my experience with the car so far: light years ahead of the C6Z as a vehicle. No more Suburban dash board parts is appreciated :-)
