i think both this bikes are priced differently right? and it's a very different bike... not just the components... one is an alloy frame and the other a carbon frame..

definitely the team carbon if you can afford it...either ways, components wise on both bikes.. there is high chances that you will be upgrading it anyway.. so, why bother???

let's look at it this way.. on the 105 team carbon... there might be a chance you upgrade the wheel and leave the majority of the components as it is... +- 10k the whole bike..

on the apex road comp... there is also the same chance (albeit a higher chance) to upgrade the wheels making it the around 7-8k...

the major question is, do you prefer SRAM in the first place as the road comp is sram equipped although the entry level group... and yes, there is possibility that you might swap some parts out even if you prefer SRAM on the road comp but it should not result in as much as RM3k unless you upgrade the entire group to a higher end one... in that case, the same applies to the team carbon as it is also only equipped with the work horse group from shimano..

so, the question is not which is better.. the question is, if you will be itchy handed come to a couple months after owning the bike as both bikes have stuff that can potentially be bettered...

and after all that.. still comes to the question of the frame after all your upgrades where it might become a bottle neck...

if you say you are worried about trashing your first bike like crashing and damaging it.. the alloy one would be of a safer choice compared to a carbon one... but other than that... there is not much reason to get the alloy one is money is not of a constraint...and even to damage a carbon one.. you need a cataclysmic crash with most probably put you in the hospital as well to make that happen..

I know there is a distributor near Bandar Puteri Klang selling their bike quite cheap. This is a new brand name "Cronus" from french.

They selling this model at RM8.5k only
ESPRESSO
Frame: 12K CARBON 48/51/54/57CM
Fork: 12K CARBON
SHIMANO ULTEGRA Groupset(20SP)
Rim: SHIMANO WH-RS20-L
FRAME 51CM + FORK 1470G/7.80KG

but they bike need to preorder

did u go to godzilla to look at wilier?
which spez tarmac did u look at? the sworks?

are you basing all this on reviews 

carbon bikes are going to be inevitably harsh if you compare it to the best steel and Ti frames out there... it is a trade off but in the trade off...you gain efficient power transfer via a stiffer frame... and possibly lesser weight...

as for the 3 models... avanti, from a brand point of view is the one where there is most ??? over it in terms of brand sustainability... we know for sure scott and specialize won't go away but avanti has the chance of disappearing from the market if the shop selling it goes bust (which i know they won't lar, bikeplus have deep pockets)

the sl3 if s-works would be a great choice if priced at RM8k... the frame was last sold at something quite close to 5k? so, 3k left for an ultegra group + cockpit + wheel is kinda impossible to achieve...

at the end of the day... you have to consider other factors like... does it have the right size for you? do you like the bike itself (Aesthetically)? do you like dealing with the shop that sells it?  my final choices would personally be between the scott and specialized (s-works or not).. for close to RM8k... no interest in an advanti...
willier??? have to be campy fan wer....
s-works and normal spez has quite a bit of difference... in terms of weight, carbon layup affecting the stiffness and ride quality of the bike itself...

godzilla is just right behind gh speedbikes in kota damansara

depends on how you see it...  the way i see it, you will work your way to it.. definitely there will be some discomforts in the beginning if you get bikes that are more low down on the front end... but there are such things as massive amount of spacers to help alleviate back flexibility problems.. and as you improve your fitness and flexibility levels, you take off your stack of spacers one by one...

it's like saying you are still a P driver... should not drive manual, why not buy an auto car first and once you are more experienced only you come back buy a manual... sounds more like he is hoping you buy 2 bikes from him...

if you are that worried about frames which is more veered to race geometries.. you can or the rep could have recommended you other spez like the roubaix for instance which has a slightly different geometry and still almost quite as good as the tarmac....
internal cabling is more to protect the cables as it is not exposed to the elements.. but it's a nightmare to run the cables which is not your worry if you give it to your mechanic to handle it...

not a deal breaker... in fact.. more reasons to buy fully shielded cables like nokon, i-links...
