I have my up! for nearly 4 mounth now. One of the last 2014 up!s, produced end of April (without tyre control but the "new push down reverse").
The 2015 up!s (since May 2014) can be identified by the tyre control button next to the 12V in the middle.
Many pics of my up! in the link (signature) ...
My first Polo 1982 had leatherette seats (an ex company car of my father).
I chose the "Salsa" seats - but I like the light grey Groove up seats with the white stripes and the orange stiching!
I drive less 2500 miles a year. So, the extra energy for the 300W booster was to unsecure for me. I will have battery problems in winter anyway. But I have Fender basses, guitars and (tube) amps. So, I had tears in my eyes not choosing the Fender system.
Yeah I have the 12V in mine. Yeah I realised after I posted ha ha, Very nice UP!!
Well this is my 1st Vw, I do share a Nissan Qashqai 1.5 diesel which is great, we have leather seats and built in sat nav etc. The UP is a run around for myself, same as yourself I don't do much mileage.
I do love the things I have in Maddie like the heated seats, heated mirrors, fender system and the M&M is great. Still trying to use that thing! ha ha.
