yes but the best thing anyone can do is buy original manufacturer tools, its hard and costly to have all of them, one must start with the vehicle we do the most and know best how to. there is no need to get involved with all makes, that is not how the money is made for many reasons, we are humans and not robots, we can not memorize all this crap and will never specialized in anything. it is humanly impossible and too costly anyway, every area is different, in some areas there are more people with american car, others have more japs or euros,  so one most choose the area you will like to work depending on the vehicles you do best, and the tool you can afford, then expand, why will anyone spend 10k on benz to work on them once or twice a year. original tools are now cheaper than ever, just start with one. specialize in one make, the best make you can think of that is popular in your area. one example if  a customer has a honda and is looking for a shop and sees 2 shops, one is called  paul's  general auto repair and the other one is call paul's  honda tech, you know where that customer is going. that shop will always be full and they probably don't even know much about honda's either but they got all the spare parts i n the world to try. i don't have all original tools either only 7 makes, too many makes but this are the customers I have. i don't  do most european cars, or rather hardly any. my policy is if i can't do them 100% I don't touch them. anyway I thought  this post can help someone.

 yes matronix and also 912guy you are both correct, here in usa we are lucky in that sense, we don't have half  the vehicle makes you guys have over there, so it is easier for us to make such selections, I assume you guys don't have such luxury as all this vehicles are everywhere in your area and one is as important as the next one,I understand now the importance of this tools in your area, hope autel does too, and fix all issues, also noticed many times that our software are different, they are not developing yours as they are ours and not fair either, it should be equally distributed specially when we are all in the same website, another autel's  mistake in every sense of the word. but that is another subject. 

 I have an original advi with a couple of vehicles, no euro though, and although it is a great tool with some great features and engineering functions it is not a great diagnostic tool, a good addition yes, not for the vehicles I have anyway, in comparison with original manufacturer tool. I assume it may be different for europe but for usa vehicles it is best and cheaper to buy originals manufacturer ones.  advi is very expensive, you could blow  50k or so easily. yes autel and vag group is more like vas and odis functions, I haven't yet been able to do anything on this vag vehicles, all this codes one must used  just complicate things so much and takes too much time. I have a neighbor with a vw and another one has an audi, they keep asking me how good this cars are and I keep telling  them is a peace of sh**t and only the dealer can fix them, and to go get a Gm, I don't know if is true or not but I know I can't fix them  don't even want to get involve with to be honest, have way too much headaches with what i do.. 

 great tip thanks , I have seen the tool even been to their site a few times but never bought it. I have tried vas and odis and they are way too different to what am used to. i will give it a try though, thanks buddy
