What are the GRM Classic Blunders?

Though it might turn into something a bit too "inside baseball,"  another thread had be thinking on what are the GRM Classic Blunders?  

For original(ish) source material, this is pointed back at Wallace Shawn's character, Vizzini, from The Princess Bride.  The classic blunders listed there were:

• Never get involved in a land war in Asia
• Never go up against a Sicilian when death is on the line

Should we attempt to collect the GRM equivalent?  I'll start with:

• Never get involved with a Land Rover Discovery
• Never accept a free Lotus Europa project
• ??

Never get it on your hootus.

Rust free Michigan is not the same as Arizona rust free.

Whatever time is estimated will be double.

You/they are never "gonna fixer up one day."

Always follow Stampie to a second junkyard?

No, wait

"Never turn down the free car if you are first in line."

This year's challenge rules changes said:

R-compounds of unusual size?

I don't believe they exist.

Never buy more Miatas than you need.

(You generally need one more than you have, though)

Never stop believing you'll finish all those project cars.

Never shut down craigslist/Facebook marketplace when YOUR PRODUCTIVITY is on the line

There is no such thing as a cheap Porsche.

I'm in the lead in my Miata which is obviously superior, and yet HE GAINS.

INCONCEIVABLE

Not knowing what I got, Bro.

$2000 budget, we mean it. 

 

Telling us not to hotlink or to just ignore a thread...

Never assume park will hold the car after you remove the driveshaft.

Never get involved in a political topic in the meme thread.

Never go up against Margie when banishment is on the line.

Talk me out of.....

My name is Calvin Nelson.

You have lodged incorrect budgetary accusations against my father.

Prepare to lose. 

If you need a super technical expert answer about some obscure field or technique or object and you need the correct answer right now, ask on the GRM forums first.

Beware of scope creep

• Never accept a free Lotus Europa project

Oooof. I feel this in my core, every single day.

Always stock extra 10mm sockets 

Ugga-duggas is a unit of torque 

Always buy Maserati Bi-Turbos in pairs.

... unless more of them fit on your trailer.

Always make sure the old O-ring from the filter is removed when doing a oil change...

This is the one that always got me, which of course dramatically increased the price of projects. 

For instance when I did the track rat NA Miata build. "Hmm, well I'm upgrading to Sport brakes for an eventual motor swap. Since I'm also putting on coilovers, let's go ahead and pull all the control arms, have them blasted and powdercoated, put in poly bushings, and use all new OEM bolts and nuts to put it back together since all this stuff is 22 years old."

I'm very a much a "while I'm in there" type person as I hate rework.
