Make a decision ...
Litigation is not a friendly game played by friends .
Form your position, take it on.
Remove all sentimate from your mind , family trip, Aussie made etc etc .. It does not matter or help imho ..I know it's hard , but the court don't care . Facts facts facts and more facts . Diary , times , calls , emails ,
Product is sub standard , obtain legal advice and make your demands .. Easy as that .. You can't be friends with them , mates are not what you need a solution is.
Me personally full refund or replacement no question , you have major structural faults if susp needs rewelding.
As Rumpig posted that company new the possible fall out and acted swiftly and bent over backwards .
Your guys made Their first attempt at repair and indicted Thier intentions . Who patches cavass on a new unit there goes 25% resale They had a chance at fixing it .. Get a valuation done as well.
