I'm with Troy and Longfella ... Things break, and mechanical failures can't be attributed to a particular builder.
To whom should the mechanical failures be attributed?
I made my living fixing complex mechanical systems-- so I get that sometimes something slips through the cracks, and something bad happens. We bend over backwards to make sure it doesn't happen, but sometimes we get a bad part or one of the guys misses the root-cause of the problem.
The problem is, this isn't a sometimes situation.
One point is a point in isolation. Two points is a line. Three points is a trend. This is a pretty well established QC problem that requires either a change in suppliers or processes. It has nothing to do with whether or not some guys get a good car, or even if the majority of guys get a good car. If a company can't say that almost everybody gets a good car, then there's an issue-- "custom built" or not.
Back to my business: what we do is complex, and it isn't cheap. There is no shortage of people who look at their equipment and think, "Bob's Heating/Cooling/and Coin-Laundry Repair can do this for $42.50/hr. Why in the world would I pay $98.00/hr?" It works for some of the people some of the time-- but when the chips are down, and it's 6 PM on Christmas Eve, and $40,000 worth of fresh meat is 60*, and "Bob" is drunk down on Key West... that $55.50/hr savings starts to look like a pretty bad investment. I don't pay my guys $16/hr-- they make a professional wage because they are professionals. If we have a QC issue, more often than not the guy takes care of it on his own time-- not because I'm a slave-master, but because it's an embarrassment regardless of who or what was at fault. It's our name and reputation on the line. It's personal-- for the guy, and for me.
Quality costs money. America was built on people paying for quality and getting it. We have mostly forgotten that, and will buy an unworkable piece of junk cast in some mud-hut in east Asia if it saves us 20% (then spend 35 hrs massaging it to kind've work). I had to have my thinking seriously recalibrated regarding what a quality replica speedster would cost. Most of us have not undergone those kinds of recalibrations.
To be blunt: Intermeccanica and Beck buyers don't seem to have these kinds of consistent mechanical failures. It's not to say they're aren't some isolated small glitches that need attention, or that Carey and Henry are perfect-- it's just a statement that is borne out by the record.
I bought my Intermeccanica as a "coach" in 2005. It had no running gear. Henry was concerned that he iron out any potential issues, so he installed his own engine and transaxle and drove the car around for a couple of weeks before he took his stuff back out and shipped me the car. I have had zero issues. Not one. Ever. So when I hear, "these are custom cars, and of course there is going to be issues", I cannot relate-- either personally or professionally.
After his VS supplied engine shelled, Will Hesch was given a $5000 credit to go get the engine he wanted, built by the builder of his choice. I can guarantee that Will's new set-up cost well north of $5000-- and that's kind've the point. Well built VW engines are no longer a $1500 proposition. The "price-points" we're all used to are no longer relevant. A $20K Prius is irrelevant as well. This is rapidly becoming an expensive hobby.
Stuff that is not guaranteed to break costs more than most people are willing to spend. The business model that I think is crazy to employ, and even crazier to defend is to hastily assemble marginal running gear and components, then rely on after-the-sale goodwill credits for the not-insignificant number of buyers who experience disappointment or worse.
“Does the Lord delight in burnt offerings and sacrifices
as much as in obeying the Lord?
To obey is better than sacrifice,
and to heed is better than the fat of rams." (1 Samuel 15:22)
THIS is why there are so many cars for sale with <1000 miles. They aren't Becks, and they aren't IM's. Buying a car shouldn't be like buying a raffle ticket.
A man doesn't always get what he pays for, but he always pays for what he gets.
Always.
Forewarned is forearmed.
