As others have already pointed out and described most features of this set, I might just make my review shorter by making a concise pro & con list.

Pros

• 1. Instruction guides came with a cardboard in a bag: hopefully from now on, all instruction guides will be crumple-free!
• 2. Wide range of pieces: This set comes with many different pieces, and obviously, a lot of them are red. A motor and a battery box are included (you might start thinking and working it out already where to install them other then n to this set...)
• 3. Motor function! : As explained above.
• 4. Great building experience: Very few repeated building and steps, it makes you impossible to get tired of building whether or not you want to finish building the whole thing in one go.
• 5. Being concrete and strong: In general, most parts do stick together firmly. Lots of pin-to-hole work makes it very concrete.
• 6. High complexity: I believe most Technic fans would love complex building experience, the more complex the better. The gear work in this set is very complicated, and very packed. Some pieces are hard to set into their place because space is very limited for you to put your finger there to hold it tightly.

Cons

• 1. Bags are not numbered: I had had the impression that sets of recent years have their bags numbered for easy building and sorting. I was surprised that they didn't this time. Having some 1200-ish pieces all in this box at the same time was a little inconvenient, especially there are quite a number of big red panels and gear-related pieces.
• 2. Appearance: As others have pointed out (and other critiques out there on the internet) that the look of this set is a little "skeletal", especially at the front in my opinion. Probably the V8 engine should be hided from view first, then the motor function can raise the hood to reveal the engine. I guess it would be more appealing that way (for example, when you are showing off your set to other people). However, Model B does not have this issue.
• 3. Hard to remove battery box: In the Main Model, the batter box is placed in a rather "difficult" location: You will have to pull 2 red pins out in order to take the battery box out, and the 2 pins are half-hidden by panels. But in Model B, I can see the placing of battery box is better planned, as in, not stuffing it to the back in the last minute of the build.
• 4. Another minor issue is that a particular group of pieces was near impossible to deconstruct! You will need a lot of strength for it and it nearly broke my nail. You will need to deconstruct those pieces if you want to build Model B after the Main one.
• 5. A little disappointed that the motor function does not include running the car forward @_@ . It was only meant for the doors, hood and the spoiler.
• 
  

To conclude:

A great set with a reasonable price and a great set in your collection :)
