Vauxhall frontera

Description:

Vauxhall frontera 2.2dti
Runs and drives but battery keeps going flat and I've checked everything but can't seem to find out why
It's one of a kind haven't seen another one that's been done like this
Haven't got the time to get it done
Ain't in a rush to get rid of it
After another car or maybe a van but I'm open to offers
