expensive haha! it was alright for a while but I think they only fixed the first part of the problem. Looks like they're still loosing the vacuum assist so this weekend I will be checking all the vacuum lines for damage and the vacuum pump for wear. Hopefully it's one of the lines leaking, but at worst it's about $300 for a new alternator/pump setup and that'll be pretty easy to switch over. Heaps of fun driving around though!
