Seems like us 840i ers are scarce here lol. I wanted to know if those who own and 840i coupe or gran coupe, do you feel like it has adequate power and you aren’t missing out on the v8? Also anyone with an 840i done any mods yet like tuning or exhaust upgrades? Thanks!

The 840 GC has way more than enough power for me in the real world of daily use.

My only custom touch has been to replace the Ivory White floor mats with black in the interests of practicality. OEM of course…

Yep as Seaford says, more than enough power - especially for UK roads, and I think it sounds great too. Always loved a 6 pot, and it’s exceptionally smooth too as most straight 6’s are. Also taken out the cream mats and put OEM rubber ones in, however now it’s summer I’ll put them back in as they do look really nice. I’ve got a Vax Spotwash that I’ll use to clean them.

Not done anything mods wise - genuinely don’t think it needs it.

I just got my 840 and have some plans for modding it. I agree things are scarce but I believe with the B58 there is a lot of commonality. Will post my list of ideas later for your thoughts

[Sinister840]

This is my parts list. Folks on the forum told me I should have bought an M8 with all this. The truth is, I wanted a B58 and something to build over time. Plus, I couldn't afford an M8 at the time of my purchase.
