I have a 50i TT V8. Love the torque, hp and sound. The 35i was not even considered never even drove it.

That said theres a lot going under the hood. If you can wrench on it a bit and are willing and able to google some issues then it’s not bad.

I fix pretty everything on my last 8 cars. (Mostly VW). I’ve got about $3000 in repairs for the last 2 years with this X5. Had a major fix recently had to outsource for $1600.

If I wreck it tomorrow I’m buying another V8. Might consider a N63 TU. At least that engine is a generation newer.

Hope this helps.

Oh yea the BMS stage 1 tuner is great! There’s no way a 35i or diesel will have a chance.
