ive found some one who is selling a ionic wfp system on a trolley cause theve been using it to wash cars at a show room and they cant get on with it cause they dont understand back wash and flushing etc if i bought it id only need to take the wheels off and fit in my van , according to the receipts theve got its a year old and they paid 4 grand for it and they will sell to me for 1500 but i may get them down to 1250 does any one think its worth it
