Yeah, as for maintenance differences, there's very little that's different between a Turbo and an NA. The Turbo hardly ever needs any maintenance on its turbo parts. The maintenance that's often done is exactly the same as on an NA:
- clutch $1000+
- ball-joints $60 on early, $500+ on later cars
- wheel-bearings $100 front $250 rear
- water-pump $300
- belts $400
- CV-joints $200
- brake rotors & pads $250-400
I had 5 years of trouble-free daily driving sprinkled with full-bore track-racing about once a month. The parts that needed maintenance are the same for both cars:
- tyres
- brakes
- fluids (brake, oil, tranny, coolant)
- clutch
The Turbo only costs $2-3k extra over an NA. Those who are considering an NA over a Turbo will spend the same on maintenance for a slower, less fun to drive car and pretty soon you'll see them asking one of two questions:
"How to get more power out of NA motor?" or
"Can I turbocharge my NA?"
After futile efforts and spending $5k+ on NA upgrades, you invariably see them sell the NA and buy a Turbo...
(no one
EVER sells a Turbo and buys an NA...)
