I have a 2011 6spd manual QV (sunroof/Bose stereo, etc) just about to tick over 150K km
I can’t think of another small car that is as much fun or engaging (at the price point). The only thing I can think of replacing it with is Stelvio Ti, and they’re hardly comparable classes.
Bluetooth (BT) is easily supplemented with a $5./ eBay BT/Aux in USB dongle. I can stream from any phone/device and the in-car BT was always happy to connect to my iPhone 6, 7, X for calls/Siri etc from the steering wheel.
Cam-belt schedule for my car is every 105K km or 5years. 4years if it’s a crap environment.
I would have another, specifically a blue QV with sunroof and all the toys (like mine) - if I could find it.
I’ve been through:
Aux/Cam-belt and water pump change
Set of tyres (Michelin PS4)
Front discs and pads (OE Brembo)
Front engine mount (OE)
Thermostat (OE)
MAF / Pre cat O2 sensor / Turbo hose (last week)
Just about to do the front brakes again.... (car lives in D)

Had to repair the rear wiring loom in the hatch (think the later models have this sorted)
Otherwise the car has been great, it’s never left me stranded (limp mode is pretty flat though)
My car lives in D, my son flicks it into D if I forget or are not quick enough
Maintenance has been easy (messy oil changes aside)
If you want the manual, I would get an early car. They’re cheaper and have more toys. I’m not put off by high mileage on Alfa’s, it’s condition and servicing that matters.
Cambelt is not that spendy or difficult to change, and not nearly as convoluted as the Busso.
I wouldn’t leave it though, get it done with the pump when in doubt
You will endanger your license and giggle a lot when it’s in D - it’s a brilliant car.
