suppose he needs to weigh up the cost, maybe rental is cool but if he doesn't know what he's doing the car can fall on him. I'm sure he can get a mechanic for the Honda - and if even, could flip it for spares to other Honda owners and maybe get a new car. Up to him - i see it has high milage too, so well used.

honestly, there will come a time where we will be unable to repair our own vehicles, either through the loss of knowledge or complexity of electronics and 'manufacturer locked repairs' So i'm with you with the DIY while it lasts.
