I bought the 630 plus and was a little disappointed in what it can do (initially scrolling through the menu)
I then performed an update and now it seems capable of much more.....what i would have expected in the first place.
One of these days i'll probably get to execute the higher functions for real.

 

Check what the other models can and can't do. I got the 630 specifically to do abs diagnosis and brake bleeding from memory the 510 won't, but it will do other things the 630 won't.

Or pay 1400 and get an 808bt

 

Since I am not in the business of maintaining several Suzuki's I will flag the 808bt. Problem is that it would take a day to sort through all the plusses and cons of Foxwells range. I have learnt one thing though - if it is not mentioned then it won't have it. I have looked at the 510 but it looks like it can only be used on a single model. The 510 does say it can do ABS bleeding. What sort of things can the 510 do that the 630 can't ? Just a couple will do. he 510 says one car only and you have to buy other makes separately.

 

Thats the biggie for me, the 630 just plugs in and works, except on some jap import Nissan's, fugas in particular.
Ford xr6 ( touchy Aussie rubbish electronics) and the zuke are fine. Seems to read most other stuff but considering I only bought it for the gv and brake bleeds its surprised me and has become the one that sits at the front of the bench and gets grabbed often
