Is there garage standard after market car diagnostic tools out there? Any suggestions would be welcomed?

Not quite sure what do you mean either, but if you mean a place to get decent diagnostic equipment, I'd personally recommend http://auto-testers.com/ , they 've got really good and inexpensive devices, I've got a few of them in my automotive garage (EDIA5, TCR3, ZCR-3) You could always google other retailers, there is an expanding market for diagnostic tools.

Theres plenty of high end diagnostic tools available. Snap-On, NexiQ, OTC. Google is your friend. Be prepared to spend some $.

I bought most of what I have from the tool trucks that come around. Expensive sometimes but the payment plan is great. Buy the high-end when you have to use it every day and lesser quality when not used as much.

I have had a look round and found some. Which brands and models would your recommend, bearing in mind their is no financial restrains?

What do you mean to say? I am new here.

I would think that garage standard tools would take up a good sized room.

You said that it's expensive sometimes.
