Dumb Question Thread - No Flaming Allowed

[PSUEng]

Not sure if this qualifies for Dumb Q thread, but I'm negotiating a deal on a 2026 X5 xDrive40i, build to order. If anyone can provide insight into what a "good deal" is, I'm open to it. No trade, Performance Center delivery; should be an easy transaction but some of these dealers just insist on the add-ons, and just really seem to hold on to every penny. I know people have to eat and business is business, but this price discovery is painful.

Is this a normal bumper-fender gap on a front bumper? Car's in the shop to have the front bumper resprayed and refitted with new mounting hardware, this looks like too big a gap to be correct fitment correct?

What's the rough lifespan of OE rubber RTABs (Z4M variant) with vorshlag limiter shims installed? I had them installed when I got the car at 45k miles, now I'm up to 105k miles 7 years later. Are they for sure cooked? The ones that were on the car with 45k miles were absolutely cooked. Do the limiter shims make a huge difference in lifespan? Also, is there any disadvantage of moving to spherical monoball RTABs when I replace? (car is street only vert, lots of freeway miles)

The limiters should help yes, but I also think their lifespan is heavily dependent upon install technique (clocked correctly). But with 60k, they're surely done. Get solid anyway.

PSUEng, BMW doesn't list the o ring separately for the coolant sensor, but it's used on other cars, so you can buy that. Part number 13621743299

Also, it is definitely included in the wolfn8tr kit, installed one a month or two ago

Thanks! I must have missed that in the kit diagram, I'll take another look!
