Hey gang, the EV experiment didn't quite work for us, so will sell our immaculate 2021 Tesla M3 LR, and plan to buy the G70 instead. Hope to get some answers here 
1. How quiet it is inside the cabin at 70-80 cruising speed? Feel free to compare it to any car you want, or simply in your own terms. I know it's not going to be S-class quiet, but maybe against the G80. I test-drove a '21 G80, and it wasn't as quiet as I expected, but acceptable. I'm afraid the G70 will be noisier, but hopefully still tolerable, especially over rough asphalt. I also have a '21 Palisade that is very quiet on smooth asphalt, but borderline intolerable over rough one. I don't want the car any noisier than the Pali.
2. Can somebody verify the 3.3T engine has solid valve lifters, meaning 60K-mile valve check/adjustment needed? That's a bummer, and a straight cost-cutting measure, as there's ZERO justification for them with a paltry 6,250 rpm redline. My Palisade is the same. Hope that's not the case, but maybe not a deal-breaker. But a big detraction, at least. Does anybody know if the 3.5T is the same? Thanks.
3. What kind of LSD (differential) does the SP 3.3T have? Is it a clutch-type, or Torsen? Hopefully the latter, but doubt it, since it's not mentioned. I know it's fully mechanical, which is fine with me. But they just become open over time, due to spring pressure loss, and/or clutch wear.
4. Any other comments welcome. At least I expect it to be more or less free of major defects, since it's on its 5th year already. But any new stuff could be problematic, like the half-a$$ hybrid dash. Ha ha. Hopefully the HUD displays blind-spot info, like the Pali. Thanks guys.
EDIT. Forgot about this one, that my wife is asking: 5. Is it safe to use regular fuel with the 3.3T? I think it's recommended, vs required, but curious if you can still drive the car normally (albeit with less power), meaning also being able to floor it if needed. And if no pinging, knocking, or any other undesirable behavior. My ex-F150 3.5L Platinum also said premium recommended, but ran like crap with regular, so always had to use premium. The issue where I live is it's 60 to 70 freaking cents over regular, rather than the 10 to 20 cents I've seen elsewhere. Thanks gang.
