I lead a sheltered life and only came across these the other day when my local garage brought one along when my 1970 MB 300SEL would not start.
I'm too embarrassed to tell you the problem with the Mercedes. [try holding the auto gear stick in park while cranking the motor
]
But it has set me wondering whether to invest in one. I need one with lots of oomph as I have a 5.6 litre V8 and a 4/4.
What should I be wary of and what do I need to know please?
Can I start the (2013) 4/4 without attaching it to the battery terminals?
