Most juvenile moment in your M635....

[Andy 85 M635]

For me it was today! I was first in line for the green arrow and had a suped up civic behind me. I didn't pop the clutch or anything, but I quickly mashed the gas just right while simultaneously letting the clutch out (10 years of experience with this car) such that I broke the rear wheels free and had to right myself going into the turn as I quickly grabbed second, leaving a black arc of rubber behind me. Left that unsuspecting Civic waaaay behind.

Yes, I'm a grown man in my 40's, but I wasn't speeding and....it was fun :-)

Soon after I got my M6 I was demonstrating (read-showing off) for a buddy riding along. I tromped it it going into a right turn and showed him a rocket ship on rails doing a 90 degree. Thinking back on it and imaginning if it had broke loose and there was another car coming up that side street I get to feeling real stupid.

one of my favorites is when I litterally 'smoked' a Mustang GT, we were 'playing' on the freeway then got a wide open freeway and went top end....his car litterally started smoking and I left him behind.

in one respect - it was when I purchased (her) without inspection via Au!oTr*der from a lawyer (a shark from a shark?) and didn't expect "Don't (specifically) Ask Don't Tell" to be in effect with regards to condition representation ... but I've come to love (her) despite a few flaws .. because (she's) still sexy, has her sche!sse together, and responds well to TLC. :-)

My most juvenile moment with my shark (my second one) was when I let my friend, a street mechanic, borrow it. He took her around the block and while about 50 people watching he turned back onto the street - drifting her @ss! What a sight! I didn't do it, but i witnessed it! Our sharks look so sexy drifting around corners!

...at SE Sharkfest last year. At a light on the way to Sunday breakfast, leading a school of Sharks. Blasted off sideways, squawked in second, over the rise M88 singing. Huh huh.
Looked back at empty road.
Nobody. Came. With. Me.

Uncoolness pervaded the rest of my morning, but that was all back before I turned 66 and got maturity.

I won't go into details. It was a couple years ago, and involved a great deal of tire smoke, a parking lot with other bimmerphiles, and a warning from management.
