have had my 2003 one with now 360,000km on it for the past 12 years.
Apart from Oil/Filters/Tyres/Wiper Blades/brake pads I have spent about a grand total of ~100euros on it until today when needed to order new front Brake Discs/Calipers for it. But still 360k km on Original Discs ain't bad.
So about 200 euros apart from regular Consumables in 12years and about 200,000km I have had it.
I try to keep a good eye on it and look for anything that might need doing, but there's rarely anything that actually needs to be done...
Still on the Original Spark plugs, clutch & Have never changed the gearbox oil on it.
On the Other 2012 Jazz we have in 5years I think I haven't spent anything at all apart from Oil/filters lol.
