The Mercedes 300E has been a pain in my neck since I got it! It barely ever starts first time for me anymore.
Nipping out quickly with bare feet, I'm not surprised when the car does not fire up first time.
I try a few more times before pumping the gas with my bare foot, working my toes and sole over the large pedal.
It's all fun and games until the cranking begins to slow and I realise my time is limited before the battery goes flat!
