Who honestly thought this would be a good idea. Probably the same dude who is charging $1k for it with a collapsed spring perch in addition to the ruined finish.

this is the kind of guy that’d zip tie his front bumper cover together with rainbow zip ties.

The finish was probably already ruined before the Line-X

Oh man, that’s going to look sweet in a week when it fades out and gets dirty, also looks like they put it on with a roller -because of course they did.

Why is it covered in bedliner?

Probably had a shitty paint job with dents, so they halfassed repairs and painted it with bedliner.

No clue.

Slathering it with Bondo and then rattle-canning it is half-assing it. This is eighth-assing it.

Yes, but there was no reason to ruin it even more.

Because who needs a Cd of 0.32 when you can have 0.47? That is more, and more is better. I have to say, I don’t hate it. I’d love to stop giving a damn about my car’s finish for a change.

I mean, I don’t really care about finish, but why ruin it for everyone else who may own it in the future?

I’ll speculate it’s because the W210 is usually a POS, so why not have some fun with it? It would definitely get a lot of attention, especially up on a flatbed trailer :D

I always wanted to do this to an older truck or Wrangler... It’s the perfect solution for a vehicle that is driven off-road (it doesn’t rust, it doesn’t get scratched in a way anyone cares about, etc).

Shit Merc with a finish to match.

You got me thinking so I did a little looking into surface roughness and drag. I found this graph from NASA. The Reynolds number for a car going 30-80mph is on the order of 1 to 5 x10^6. For a golf ball at 150 mph it is around 1.5 x10^5. For golf balls the dimples improve the Cd. For cars, not so much.

My non-engineer understanding is that the dimples (while spinning) greatly reduce the low-pressure area behind the ball, which is often the biggest source of drag for any object moving through a fluid. A car doesn’t spin, so apart from some minor flow disruption (or convergence efforts) near the back of the car, roughing up the surface is not going to help at all.

Still more reliable than a W220.

Even if it’s 90% uneven and pinholed bondo, if you rattle-canned it with rustoleum, it would look better than rolled-on bedliner.

Depends on the abuse you intend to subject it to. The inside of my MR2 is rhinolined.

Spinning isn’t a factor in how the dimples do their job. The Reynolds number is determined by the nature of the fluid (air in this case) the speed of the flow and the size of the object. So, if you were to increase the size of the golf ball to a beach ball, the Reynolds number would increase and the dimples would then increase the drag, not reduce it.
The golf ball size and speed put it in that sweet spot where the dimples make a big difference to reduce drag.
As for how it does it, the dimples allow the airflow to stay attached to the ball longer.

Like, I get floorboards and whatnot, but bedlining the entire exterior on a street car?

Also has wheels from a 203 coupe, which have the wrong offset for a 210.

Oh no-here I was happy with mine-I must be wrong. Tell me what went wrong with yours?
