Well to be honest I don't like it, I think the huge motor hiding the pilot angle of view is dumb...
There are stickers with flames and a head skull, but what else ? Maybe the fact that 6 motors are included ? Not sure that it will add some great value (plus these can be found elsewhere).
It reminds me the Lego Racers theme (somehow)...
Small sets ? No, but it can vary. Only sets with interesting parts (big wheels, caterpillar tracks...) may be interesting.
I mainly invest in sets with power functions because you can't get enough of power functions when you are a lego technic fan -which means you are an advanced builder-
And biggest sets because they are bad-asses, have big parts and -as always- power function.
Otherwise, sets that are compatible with power function (but don't include the motor): sets that are "power function ready" (ready... to receive one).
I have to insist, it's very important, so much that these motors are best sellers in my country on amazon (17th best seller in construction toys, including legos, playmobils...).

Yeah, better than a lego city fire brigade. I can't say anything more.
But be careful, technic sets are mainly seeked after in europe, so choose your sets wisely... (after all, maybe you're right to look at that hotrod, as an US reseller ?)
Yes that's the great part for technic sets (in investment I mean), there are no surprises and you can easily have your eyes caught by retired sets still on shelves of a B&M shop because it's 2 years for all sets, except for the biggest one which stays for 3 years.
On spring/summer 2014 you can find sets from:
=>2014 + 2013 + the 2012 biggest set
On spring/summer 2015 you will find sets from:
=>2015 + 2014 + the 2013 biggest set
On spring/summer 2016 you will find sets from
=>2016 + 2015 + the 2014 biggest set
and so on...
So to finish this muddled post , IMO you can look at that set but whatever you will invest in or not, you have up to the end of 2015 to search for deals. And before that, look on amazon to see if it's a good seller or not (and brickpicker stats of course, to see if it's seeked after or not).
