What is the difference between a Citroen C1 VTR+ and a Citroen C1 VTR+ EGS?

EGS is a semi automatic gearbox. Test drive that version first though as it has been jerky in other models. Good car though. Very advanced. Haggle hard as Citroen dealers are susceptible. Get a quote from Drive the Deal on the net. Photograph the screen as it won't allow printing and pop it under the dealer's nose. If he won't do it find another dealer who will. They can match it. It just depends how business is at the time.

As above, but avoid these semi auto flappy paddle gearboxes like the plague.

Guarantee 100% that's what will end the car's life, probably after 5 or 6 years when the gearbox goes bang and costs more than he car's worth to fix.

Electronic Gear Selection, allows you to change gear without a clutch, can also be driven manually
