Over the years I've had several 911's as daily drivers (1970 through 1995). I kept on top of all maintenance before they became big issues. Putting an average of 20,000 miles per year on each P-car, probably spent about $1,000/yr for maintenance but well worth it to drive a Porsche to any place I needed to be (work or play).
I would imagine that if I were on my death-bed, my last words WOULD NOT be "...I'm sure glad I got that Celica instead of that 911'!!
IF YOU CAN DO IT...DO IT, TOM!!
...I'm just saying...
