Go to the big box store and get Chinese parts for your GM. That is what I do. I flat out refuse to go to the dealer for ANYTHING on my pre-obama chev van. If I can’t get it from the aftermarket parts store i go to the self serve pick a part. Rarely do they ask what the part came off of. They have flat rate pricing. Normally a part is <15 there. A complete engine is 125 bucks.
I bought it a month or so ago. I am not proud but I had 600 bucks to spend on a van and I needed it with in a week for a new job.
it was the first van to come along that fit the requirements so I bought it.
I don’t plan on keeping the van long. its making me money and I have already started the Ford Econoline/Benz sprinter fund to replace it.
I solved the problem by... not buying GMs.
I find I have to go to the junkyard a lot less, as a pleasant side effect. Even my Jaguars break down less than my neighbor’s Impala.
The GM boycott didn’t really affect me - I’m one of that 42% that wouldn’t have their buying decision changed, because there was no way in Hell I was going to buy them based on their prior track record (not just historically, but with me personally.)
